27
28   1. An expression of the form `A::m' where `A' is a class and `m' is
29      a non-static member.  In this case, operand 0 will be a TYPE
30      (corresponding to `A') and operand 1 will be a FIELD_DECL,
31      BASELINK, or TEMPLATE_ID_EXPR (corresponding to `m').
32
33      The expression is a pointer-to-member if its address is taken,
34      but simply denotes a member of the object if its address is not
35      taken.
36
37      This form is only used during the parsing phase; once semantic
38      analysis has taken place they are eliminated.
39
40   2. An expression of the form `x.*p'.  In this case, operand 0 will
41      be an expression corresponding to `x' and operand 1 will be an
