Enumeration Type Documentation

enum Associativity

Bug:

This file may not survive, but the mixfix system was getting complicated enough to pull it out into a separate file. The issue I anticipate is that mixfix is statefule, so we may need to attach the mixfix state to the lexer. That's where all of the parser state lives, because Bison doesn't provide a straightforward way to have a parser object.
