Okay, I think I got it. Pretty exciting, especially given I don't know
ruby at all. Comments appreciated, for sure, as I'm not positive that
I might be trying to fit a square peg into a round hole.
I've made a fact that loads results from a perl script.
1) The sample perl script gives output just like a puppet node
classifier would using YAML
2) The ruby parses the output of the perl script and generates facts.

value

end
