That is indeed broken behavior (and I think there is a DIP to fix it), 
but member function pointers are not really a necessary language feature.

You can use a

T function(ref S, Args)

in place of a

T (S::*)(Args)

(for S a value type, otherwise you don't need the ref).

Then, instead of

auto mptr = &S::foo;

you write

auto mptr = (ref S s, Args args) => s.foo(args);

(This is a bit more typing, but it can be automated, such that you only 
write getMPtr!(S.foo) or similar.)

instead of

s->*mptr(args)

you write

mptr(s, args)

The syntax is more obvious, it is more general, and at least some C++ 
compilers will do the same thing under the hood.
