Not yet. The interpreter is easy, but the compiler is more complicated 
in this case.

Of course not. Having some opcodes to be 8-bit kills the benefit of all 
16-bit opcodes.

This options needs to rewrite more code, but resulting code can be 
easier. I afraid that might be problem with bootstrapping, generating 
freezed modules.
