I may be missing something, but why not use a function instead of the
eqns rule?
sub run_equation { $parse->clear(); $parse->eqns(@_); };
and then in the grammar implement a clear() rule to clear the
variables.
You could also instantiate a new grammar object, since your grammar
objects basically have a private variable for the variables hash.
