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

Proposed resolution (August, 2011):

In 11.4 [class.mem], delete paragraph 4 and change paragraph 5 as follows:

A member can be initialized using a constructor; see 11.4.5 [class.ctor]. [Note: See 11.4.4 [special] for a description of constructors and other special member functions. —end note]

A member can be initialized using a brace-or-equal-initializer shall appear only in the declaration of a data member. (For static data members, see 11.4.9.3 [class.static.data]; for non-static data members, see 11.9.3 [class.base.init]).

The grammar allows a brace-or-equal-initializer for any class member with a member-declarator, including typedef members and member function declarations, and there is no semantic restriction forbidding those forms, either.
