[ Pete: Agreed. It's editorial, so I'll fix it. ]

Proposed resolution:

Change [func.wrap.func.targ], p4:

Returns: If type() target_type() == typeid(T) && typeid(T) != typeid(void), a pointer to the stored function target; otherwise a null pointer.

[func.wrap.func.targ], p4 says:

Returns: If type() == typeid(T), a pointer to the stored function target; otherwise a null pointer.

1. There exists neither a type, a typedef type, nor member function type() in class template function nor in the global or std namespace.
2. Assuming that type should have been target_type(), this description would lead to false results, if T = cv void due to returns clause [func.wrap.func.targ], p1.
