Character class set operations?by diotalevi (Canon) |

diotalevi has asked for the wisdom of the Perl Monks concerning the following question: I recall discussion of a feature in the regexp engine supporting set operations on character classes. I would like to use the character class [[:punct:]] minus [,"\s]. Isn't there a syntax to support that directly? I can't recall it and can't find documentation to support it. Whatever happened to that? ⠤⠤ ⠙⠊⠕⠞⠁⠇⠑⠧⠊
