26   1. An expression of the form `A::m' where `A' is a class and `m' is

29      BASELINK, or TEMPLATE_ID_EXPR (corresponding to `m').
30

32      but simply denotes a member of the object if its address is not
33      taken.
34
35      This form is only used during the parsing phase; once semantic
36      analysis has taken place they are eliminated.
