I disagree that "trim" is a misnomer for this function. It may be used as shorthand for "trim whitespace" in some programming languages, but it's not universal even within CS, and it's not what "trim" by itself means in English. And Clojure has already shown that it is willing to break with established terminology in order to Get Things Right. > Usually trim-functions accept an optional list of chars to trim.

I agree with the proposal for a second, optional argument to trim; I'm ambivalent about whether chomp would still be necessary then. I'd prefer the optional trim argument to be an actual set of characters (the semantics are more appropriate, and it might allow a more performant implementation), but I wouldn't object too hard if it accepted any seq of chars instead. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
