Hi, does this rewrite cover compile-time regex compilation?
E.g. regex!`^a` compiling to s.length&&s[0]=='a' or something like that.
Yes, I've dubbed it static regex. In fact it will be something similar
to this, though it will do a heap allocation for backtracking points, on
first call to match. Heap allocations are definetly going away in final
release.
You can pass -version=fred_ct -debug to dmd to see generated programs.
At the moment it's more prof of concept then speed devil, something I
might see about to change once CTFE bugs worked out. Anyway when it
doesn't crush the compiler, it's pretty fast :)
