I didn't see anything in the referenced code to indicate that it parsed anything. All it does to decide the next state is run a bunch of your test functions to see which one returns true. What your test functions do is up to them.

    You know, I think you're right. I didn't think hard enough about what $_ was in the examples I was looking at.

    Now I guess the only problem is that the code in DFA::Simple is decidedly scary. Maybe by tomorrow I'll have shaken the memory and I can start using the module with a clear conscience.


      One thing I'll note is that use strict isn't used in DFA::Simple. You may want to give it a treatment of that before actually using it. You'd want to rescind it when it calls your functions so that you can pass in function names instead of hard references.
