Expressions

Precedence and association are expressed in the phrase structure by distinct nonterminals. These concepts have to do with the relationship between the linear text and the semantic structure, and are no longer relevant once the AST has been built. Retaining distinctions between semantically-equivalent nonterminals in the AST is counterproductive:
