Rather than settle all the shift/reduce conflicts with %prec, etc.,
could it be that a different parsing technique would be more suited,
e.g. https://en.wikipedia.org/wiki/Parsing_expression_grammar always
picks the first rule so you can remove ambiguity by careful ordering.
Still work required, but different work. :-)
Cheers, Ralph.
