Having something like the "var" pattern can be useful for macros that expand into uses of match, if the macro doesn't want to expose that a bound variable will be a match pattern and therefore must not be "_" or "...". Granted, there are ways around this, but personally I think it would be nice if match supported this pattern. I would, however, entirely support renaming this pattern to something more obscure, like "match:pattern-variable" or something, so that unintentional uses stop being a problem.
I think the real solution is to have (whatever name you give) `var' be something that is matched as an identifier and not a literal so that programmers can rename the pattern. But I know from talking with Sam this would be a big change for match.
In the meantime, something more obscure than `var' would go a long way toward me not cursing Sam's good name every time I write an AST.
