Because a very specific, non-arbitrary, well-designed operator overloading RFC was just rejected. I don't know that anything has changed that would result in a different result for an even-broader (more foot-gunny) RFC. Personally I'd settle for a bind operator, comparison operators, an some built-ins to use those for a new stream API bootstrap. That would already be huge, but the voters seem not favorable. :-( Side note: I was asked elsewhere if bind was like pipe, since they look alike. Yes, bind is simply a "fancy pipe", essentially, for some contextually-relevant definition of "fancy". We should still add the non-fancy pipe as well while we're at it, but that's a separate RFC. :-) --Larry Garfield
