Are function pointers compile time constants?

I just want to point out that this *should* be doable in D.  At compile
time the function's address in the object code is a placeholder that the
linker or loader will fixup based on the function symbol.  This is what
linkers do!  And if an function ptr is used, the function can still be
inlined; just need to keep around the real function reference through
the pointer.
