Integration with poly

[pkobrien]

Just wanted to let you know I'm making use of phalanges in my poly library and was wondering if you wanted to explore ways to increase the integration of the two. Right now I'm just using phalanges to decorate the data coming out of key events but it seems like maybe more could be done. You can see what I'm doing here: https://github.com/decomplect/ion/blob/master/src/ion/poly/core.cljs
