So, how hard would it be to provide a mechanism to do this in the same file? There's a large subset of use cases for Lisp's macros which need the &body parameter. To do the equivalent in Python/Cython, you'd need a way to specify a block of code, much like a closure that doesn't take any parameters. Interesting...
