As far as I know, the classic OTP binary syntax has
been defined and restricted in several ways so that it
can be compiled efficiently and relatively

However, from what it sounds like, future OTP releases
may support more flexible bit operations, which could
be what you want. Have a look at the relevant paper by
the Hipe group in EUC'05 for some hints. (Um, I can't
remember the title at the moment ...)
