Here's an example of the Python produced by Genny: https://github.com/treeform/pixie-python/blob/master/src/pix...

That Python is the output from this file: https://github.com/treeform/pixie/blob/master/bindings/bindi...

This is very new stuff for us but we really like the idea that we can generate comfortable bindings for many languages and never have to worry about method signatures or comments or default values getting out of sync with the C / shared lib interface.
