It's also why I = don't use rx often, in fact. The verbosity of rx is very much a question of habituation. It is to me = a very small price to pay for its numerous advantages. I recommend reading Olin Shivers's original SRE text = [https://scsh.net/docu/post/sre.html] for a well-reasoned rationale. > By the way, could forms like "[A-Za-z]" be converted to a more compact = representation? At the moment xr produces (any "A-Z" "a-z"), but it = seems that (any "A-Za-z") would work as well and be shorter. That's a close call, but I tried it and it's probably no less readable = so I made the change. Thank you.
