5 - shared memory allocator (use or link to boost::shmem::allocator)
9 - document __gnu_cxx::__versa_string, add new policies
10 (Policy-based design incorporating COW
11 vs. deep copy issues, MT scalability

13 "Generic<Programming>: A Policy-Based basic_string Implementation"
14 http://www.cuj.com/documents/s=7994/cujcexp1906alexandr/)
16 - operator!= and utility/rel_ops operators need to be made safe with
17 string and vector iterator classes. basic_string::reverse_iterator may
18 be implemented incorrectly, or need things like
19 operator==(__normal_iterator, const char*&), and swap(vector)
21 - 'do the right thing' ctor fixing needs to be done for string. This
22 is still subject to some debate on the library issues list, so I
23 suggest punting till the dust clears.
25 - fix template members of basic_string<> to overload iterators and
26 non-iterators properly. (This is the infamous hack as in vector<> etc
31 - implement __convert_to_v and __convert_from_v without "C" library
32 functions and and LANG environment variable dependencies.
34 - use localedata to implement generic named (non-MT-safe) locales?
35 Figure out a way to use ICU data, like libjava? Re-package and use
36 the glibc localedata, even if we aren't on linux? Need a generic
37 locale model that does something besides the "C" locale.
39 - make locale::classic() separate from named locale code. This will
40 improve the static linkage situation, but will require new
41 initialization code. In particular, we need lazy-initialization of
42 locale::classic(), and maybe the has_facet/use_facet functions for all
43 the required facets. The end goal is a self-contained
44 locale_init.cc, or one with transitive closure without the locale
45 instantiations (locale-inst.cc) or the named locale bits
48 - Jerry(?)/Paolo(?) work on __float_to_char.
50 - minimize ctype convertion in data facets, see numpunct/num_put/num_get
52 std::basic_filebuf, 27_io
54 - wfilebuf, get variable-encoding working and tested, including
55 positioning and seeking. (I think this may be done now)
57 - wfilebuf testsuite (getting there...)
59 - look ahead for unbuffered io, so know when multiple putc's can be
62 - unlocked __basic_file + new mutext class
64 - optimized the sentries for istream/ostream
68 - add optimization hooks (esp. whitespace eating) to streambuf
69 - add _M_begin() and _M_end() to streambuf
70 - add algorithm specializations for [io]streambuf_iterator (copy find etc.)
74 - valgrind hooks into make check so can tell memory leakage
75 Some commentary on the valgrind users list
77 - add hooks for qmtest, pychart, other for visual diffs
79 - automatic testing of interactive tests
81 - diffing generated output files
83 - provide testsuites for numerics.
85 - make check-abi needs to have full symbol checking. Scope the LSB
86 testsuite, see what's going on with the typeinfo etc. bits.
88 - try to do a better job of ABI testing, with instantiations of all
89 standard-specified types checked, not just exported symbols.
93 - compression for wide versions of basic types, not just narrow
97 - create MT abstraction layer for atomicity to pthreads.
99 - solution for threads + C++.
103 - relocations, work on getting these down
105 - issues with __builtin_memcpy and std::copy from Jerry Quinn

110 - fix dependency tracking for includes (.h, .tcc) during build process.
112 - coordinate with "C" library people the "C" compatibility headers.
114 - Think about naming all member data and member functions consistently
116 funtions: _M_verb_adverb
117 data: _M_noun_adjective
119 - A C++STYLE guide that deals with nested namespaces, and that
120 everybody can live with.
122 - exception specifications need to be reviewed for all parts of the
123 library support and utility areas, particularly <new>. Part of this is
124 a standards issue, where the 27_io standard is really in an odd
125 spot. Do the work to make this consistent.
127 - C-related issues WRT to io and filepos, mbstate_t. Seeking in wide
128 streams. May need to define operators for mbstate_t so that
129 'mbstate_t& == mbstate_t' is something that can be done.
131 - scoping/linking issues WRT to C structs need to be worked out. See
132 Nathan's commentary on cantrip, http://www.cantrip.org/cheaders.html
134 - auto_ptr: seems to be some disagreement on what is
135 standards-conformant behavior, specially on conversion operators.
137 - list::assignment operator needs const_cast
139 - a cleaner division between pointers-to-value_type and true iterators
140 needs to be drawn throughout the entire STL implementation.
142 - priority_queue conversions may be non-conformant
144 - Protect valarray::result_type (not Standard) and make it work with
145 the various helper classes.
147 - Make sure `valarray<bool> & == _Expr<_BinClos<logical_or,_ValArray,_ValArray,double,double>,bool>'
150 - All of the Library working group closed issues need to be
151 addressed. Some of them proposed resolutions are already in the v-3
152 sources, with macro-guards. Also, same with the TR.
154 - need to think about doing a .texi or DocBook manual, instead of all
155 these HTML pages. In addition, it would be nice to have a full manual,
156 instead of a lot of ad-hoc pages. Weaknesses include numerics, locale,
159 - add FAQ entries -- improve the install instructions
163 - do more doxygen manpages
