> The parser just needs a table to look up the precedence (and associativity) for a given operator. But a parser already needs a bunch of different tables in order to work, so that's certainly not a problem. Think about how you'd implement an independent parser for such a language, say for the sake of pretty printing it to html. Module A uses a user-defined operator that has been defined in Module B. You effectively cannot parse A correctly before you parse and load B, but the fact that you need to parse and load B is "hidden" in some import declaration that in turn needs to be parsed first. That's what I call a mess.
