<div dir="ltr"><div><div><div><div><div>Is there any assurance3 that a program written with Racket wil work with a future version of Racket? I expect the short answer is: No.<br></div>Any related comments are appreciated.<br>
</div>I am using Racket version 5.2.1.<br></div>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.<br>
