This doesn't really work:
- byte-code is readonly, if mmap()ed and when running function core or
CGoto
- for prederefed cores, the assign instruction needs predereferencing
- doesn't work with JIT
- There is no means to invalidate the sub, when something changed.

These lookups are in C-code mostly, so no.
