does 'eval{...}' have a lot of overhead?
not the string interpolation kind,
the 'trap on die' kind.
every rule is wrapped in an eval{} wrapper.
if the rule fails in the middle of the rule,
it dies to get completely out of the rule.
not sure if there is a way I can avoid eval,
but it would mean that a lookahead capability
would mean I wouldn't be eval'ing as much
as I am now.
