Oh, sure. ;-) Because absolutely everyone is just waiting to
rewrite all of their code with that bloat. Not gonna happen.
Anyway, this is going nowhere. The "bit.*" namespace, as defined
by lbitlib and the upwards-compatible Lua BitOp, already has a
large, existing user base and code base, built over several years.
Anyone insisting on creating an incompatible library ought to pick
a different namespace.
