The concrete use case that I got was that I wanted to replace all trailing whitespace, but leave tabs/newlines etc untouched. The current code looks like this: ```ruby newstr = str.sub(/ +$/, '') ``` I tried to see if there was a...herwinw (Herwin Quarantainenet)
`String#strip` and related methods have a hardcoded match on whitespace, defined as "null, horizontal tab, line feed, vertical tab, form feed, carriage return, space". It would be nice to allow a parameter to specify the characters you w...herwinw (Herwin Quarantainenet)
I don't really see how this would be any different from `match?` Beside that, the semantics are a bit ambiguous. `"foo".sub(/bar/, 'x')` does work, it just doesn't replace anything because there is no match for the regex. So would `su...herwinw (Herwin Quarantainenet)
