For those using Python, we just got our Python bindings for Pixie up onto pip. Repo here https://github.com/treeform/pixie-python
It's extremely fresh but our tests are working so consider giving it a try.
For those interested in Nim's meta-programming, we're generating those Python bindings for Pixie from our Nim code using https://github.com/treeform/genny here https://github.com/treeform/pixie/blob/master/bindings/bindi... More languages in the works.
