Good point.  However, note that the entire point of the %prec trick is to force
Yacc to shift when it detects ambiguity in the rules.  If another parser
generator can be told in some implementation-defined manner to always shift,
you can port the grammar over by stripping out the %precs, reformatting the BNF
as necessary, and adding whatever the other parser needs to know to shift.  I'm
not familiar with any other parser generators, so I don't know how hard this
would be.

I'm working on that.  If you can tolerate a subpar lexer (i.e., one that
accepts invalid {brivla}) for the purposes of testing, I should be able to have
a program that shows the grouping of grammatical constructs with my grammar by
late tonight.
