If you're building this framework as a bunch of libraries, that means
expressivity at all kinds of boundaries that would be strictly
"internal" in a monolithic compiler will be limited by your idea of
what may scare people. Are you sure this constraint is a good idea?
Seems likely there are good reasons to templatize a lexer and lots of
other components in a C++ compiler.
