1340. Complete type in member pointer expressions

[Voted into the WP at the February, 2012 meeting; moved to DR at the October, 2012 meeting.]

Both the .* and ->* operators (7.6.4 [expr.mptr.oper]) require that the class of the second operand be a complete object type. Current implementations do not enforce this requirement, and it is not clear that there is a need for it.

Proposed resolution (August, 2011):

1. Change 7.6.4 [expr.mptr.oper] paragraph 2 as follows:

The binary operator .* binds its second operand, which shall be of type “pointer to member of T” (where T is a completely-defined class type) to its first operand...

2. Change 7.6.4 [expr.mptr.oper] paragraph 3 as follows:

The binary operator ->* binds its second operand, which shall be of type “pointer to member of T” (where T is a completely-defined class type) to its first operand...
