What Neil said _and_ what Shivers said!
Implementing Shivers-style SREs would be a much bigger win than any alternate
pregexp syntax with differently funky backslash rules from everything else.
So, any volunteers?
This sounds fun to do, but I might not get to it in a timely manner, so
it would be better if someone else was ready to tackle this.
I think that this work ideally includes at least three additions: (1) a
procedure that translates an SRE to a Racket regexp string; (2) for
convenience, a procedure that translates an SRE to a Racket regexp
object; and (3) a "#rx(" or "#sre(" reader extension. Note: I said a
reader extension rather than macro form, just to be consistent with
Racket's existing regexp support, but perhaps a macro would make a
little more sense for SREs.
