I think the confusion here comes from your use of the word "operator" - in a technical sense, this is not an operator in the language, which takes two values or expressions and produces a new value. Rather, it's a convention used inside certain functions, to interpret a string argument in a special way. I suppose you could argue that the result is a very simple embedded language, like regular expressions, and then '..' would be an operator in that embedded language; but it's probably not how most people would describe it. As for proposing to add it in more places, it would be good to have a clear expression of why having this facility in those functions would be useful. Every extra feature adds complexity, and is a potential source of bugs both in its implementation and in code that users write which touches it. A proposal needs to make a clear case of the gains that outweigh those costs. Regards, -- Rowan Tommins [IMSoP]
