36 * In a hashtab item "hi_key" points to "di_key" in a dictitem.
37 * This avoids adding a pointer to the hashtab item.
38 * DI2HIKEY() converts a dictitem pointer to a hashitem key pointer.
39 * HIKEY2DI() converts a hashitem key pointer to a dictitem pointer.
40 * HI2DI() converts a hashitem pointer to a dictitem pointer.

50 * "name" points to the variable name.

54 * "name" points to the expanded variable name.

57 * For an index in a list:
58 * "name" points to the (expanded) variable name.
59 * "exp_name" NULL or non-NULL, to be freed later.
60 * "tv" points to the (first) list item value
61 * "li" points to the (first) list item
62 * "range", "n1", "n2" and "empty2" indicate what items are used.
63 * For an existing Dict item:
64 * "name" points to the (expanded) variable name.
65 * "exp_name" NULL or non-NULL, to be freed later.
66 * "tv" points to the dict item value
68 * For a non-existing Dict item:
69 * "name" points to the (expanded) variable name.
70 * "exp_name" NULL or non-NULL, to be freed later.
71 * "tv" points to the Dictionary typval_T
72 * "newkey" is the key for the new item.
