1 * fix/junk ambiguous String constructor overloads, e.g.:
2 String( int ) and String( char )
8 * disable this auto conv: const pointer -> bool -> string
12 * PCursor -> Pointer_cursor / PointerCursor ?
14 * efficient copy cons for List
18 * use template handle in handle.hh for strings.
20 * move towards gnu or STL?
