All you gotta do is import hy before the given hy module.
Hy uses a metaimporter to parse the Hy code and hand the Python compiler AST. So you can import any hy file like normal Python and use the code. Its that simple.
Is there some way to incorporate Hy snippets into an existing Python script?
The plan is that this would allow me to incrementally translate my Python scripts into Hy (I'd start with the easy bits, obviously).
