Yes, of course. That's a big difference with respect to Boost.Contract
where the macros are used in the user code so I can't pre-compile
stuff in the lib to speed up things. (Using pre-compiled headers in
the user code reduced re-compilation time of the users code from x30
to x2 but users still have to wait a long time when they compile their
headers for the 1st time and if they significantly change their
contracts as many of the pre-compiled header will need to be
re-compiled.)
