You normally specify them as top_precedence/second_precedence/last_precedence sets. SimpleParse' limitation is with ambiguity, not with precedence. SimpleParse will wind up "overparsing" noticeably for each operation, that is, it will parse "expr" and "word" once for each level of precedence. SimpleParse is normally fast enough that you don't really care, but optimising those cases is something that's sat on my "would be nice" list for a long time. Unlike separate lexing/parsing systems, it's a little more involved for SimpleParse to do that without losing the generality of the parsing approach (i.e. the flexibility of a non-lexed approach).
