It'd still have the problem of the global name. Consider:

-version=use_foo

but then lib a and lib b both have:

version(use_foo)
   bool usingFoo = true;


but they have different meanings of what "foo" mean. The
bool there won't trample cross module, but the version will
still set it inappropriately.


I really think using version() for features is just always
a mistake since these things do happen anyway. The only place
where it is clear is things like platform versions.
