i see quite a bit of code from zed shaw's mongrel in there[1].. to the extend that i think puma is simply a mongrel that uses threading.

you say it is using ragel; mongrel also uses ragel[2]. mongrel and z.shaw are even mentioned on the ragel project page. (and ragel is mentioned on the mongrel page[3])

sorry but i think puma could be more upfront about being an innovation on top of mongel.

otherwise nice work! code looks indeed very clean compared to unicorn/rainbows and zbattery.
