Nice trick. Perhaps something for a compiler to
consider?
I can think of two things here:
- Adding notation for indexing into binaries (like
indexing into arrays), which would just be syntactic
sugar for what you're doing above;
- Eliminating sub-binaries by replacing their
selection with indexing as above ... but done
automatically. Something for a high level optimizer
perhaps?
Best,
Thomas
