Is there any assurance3 that a program written with Racket wil work with a future version of Racket?
There have been a few non-backward-compatible changes over the last decade. Since you're using 5.2.1, which is fairly recent, I don't think you have to be concerned.
I have found that regexp functions are too slow for large data files but maybe newer versions have made a change that would speed things up. (I read something about some solution from github but I am not sure that is something I should look into.) I'd rather just install a new version of Racket at an appropriate stage, namely when my current project development has concluded. My current work around is a call to an external program which provides the regexp function at the speed needed.
You might want to post an example of how you're trying to use regexps in Racket, in case anyone has time to look at it and comment.
