This is precisely why I don't like it, because they are *metaparameters*. Having a variable length set of options where the length determines what the FIRST options are is actually really confusing, particularly because we already have an optional set of parentheses for the return types. I understand that folks familiar with Lisp/Scheme might be comfortable with it, but I'm very comfortable with both of those and I find this a bit maddening. Could be just me. I really do like the idea of separate characters for metaparameters on functions; another option would be Python/Java style decorators on the function (e.g. @type(A)), though I think in practice that might be a bit unpleasant (I really wish there were a better way to do the decorator pattern in Go, though). I'm somewhat surprised that the parser developers find the variable-length list of parenthetical clauses *easier* to deal with; it seems like a good way to introduce ambiguity in the parsing. That may be part of why the parser currently breaks when returning closures. But then, I'm not the one writing the parser, so I'm running on a lot of assumptions. I'm all for giving this time to settle and see how it plays out, of course. One thing I've learned is that it's generally a fool's errand to optimize for my use cases, at least if anyone else is going to like it. But consider this my vote for alternate delimiters. - Dave -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
