Actually, I started this thread because the C++ compiler doesn't
accept that syntax. Igor cited relevant part of the Standard that
explicitly forbids it and demonstrated with short example why it
forbids such sintax.

Igor's argument applies to

void (X::*pf)() = &X::foo; // inside Y::bar

not what I wrote which is

void (Y::*pf)() = &X::foo; // inside Y::bar

Again, the compiler won't even get to the assignment part. Just writing
a no-op like

&X::foo;

will already fail to compile.

My version, which may or may not be accepted by the compiler, is
perfectly typesafe.

Again, nobody doubts the type safety. It's access control that's
blocking your code.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
