If this is related to only VC6 and VC7.0, then a typeof-using implementation
would compile fast (and not require registration) since for these compilers
the only possible option is to use the Igor' Chesnokov's MSVC-specific trick
(not emulation).

However to stress-test it would be a good idea anyway.
