1124. Error in description of value category of pointer-to-member expression

According to 7.6.4 [expr.mptr.oper] paragraph 6,

The result of a .* expression whose second operand is a pointer to a data member is of the same value category (7.2.1 [basic.lval]) as its first operand.

This is incorrect if the member has a reference type, in which case the result is an lvalue.

Rationale (September, 2010):

There are no pointers to member of reference type; see 9.3.4.4 [dcl.mptr] paragraph 3.
