Why isn't &A::get_it (as non-static) a constant expression?
I have to admit I didn't look it up in the standard, but when
I find that every real C++ compiler(*) eats it, I am not tempted
to look it up.

*) this time "real C++ compilers" stands for:
Borland C++ 5.5.1
GCC 2.95.3 - 3.0.3
Intel C++ 5.0
Comeau C/C++ 4.2.45.2
