I'd like to see a comparison of compilation times between the old and the new implementation and the latter being stress tested on Boost.Python tests before it officially replaces the current code.
I'm not sure what you mean. The "current code" for remove_pointer, et al. for VC6 and VC7 is broken -- it does nothing.
It does, see
http://www.boost.org/doc/html/boost_typetraits/category.html#transform.broke n_compiler_workarounds_.
You want to see a performance comparison between code that doesn't work and code that does. Why?
Because we have code that depends on Type Traits working reliably on MSVC 6.5 -- and taking a reasonable amount of time to compile.
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. Regards, Arkadiy
