[Voted into the WP at the July, 2009 meeting as part of N2927.]

Proposed resolution (July, 2009)

See document PL22.16/09-0117 = WG21 N2927.

According to 7.5.5 [expr.prim.lambda] paragraph 8, the “object type” of a captured function is the type to which the reference refers. That's clearly wrong when the captured reference is a reference to a function, because the resulting data member of the closure class will have a function type:

    void f() { }
    void g() {
      void (&fr)() = f;
      [fr]{};   // Oops...
    }
