I expect chop still has its uses. Also, since $/ is going away, the meaning of chomp will probably change from chomping $/ to removing whatever was marked as the terminator by the input layer (which could even vary from line to line if the terminator was specified as a pattern). But mostly people will just have the input layer autochomp so they never see the delimiter. (The chomped delimiter could maybe be attached to the line as a property in case you're interested, if that's not too high an overhead.) Autochomping is one of the motivations for switching from "while" to "for" for the normal line input method, since "while" might think a blank line is false, while "for" only cares whether the next value is defined.
