In fact, this should fail to compile.  The fact that it succeeds is a bug. 
You should enter it in bugzilla (is it already there?)

Did you try running it?  I get a segfault.

fp is a member function, which means it needs a hidden 'this' pointer.  When 
you assign &Cls.foo to fp, this should result in the same error as if you 
typed Cls.foo():

Error: need 'this' to access member foo
