Possibly.  I'm not familiar with C++ modules: what exactly does it
entail?  You have to precompile headers before they can be used as a
module?  That sounds unusually onerous, compared to, say, D, where the
compiler just parses the source file directly and the user doesn't have
to do anything extra.
