Below is a formal list of possible optimizations, which most would agree on. We had these discussion in 2001 with damian were perl6 and perl5i took off. I'd like to work on these for perl5 core and need decisions. Most p5p hackers seem to be informed about the general possibilities and directions, but not all. We'd need this to improve general perl5 performance, and also help static compilation.[1]
