Thanks for sharing the BINDING-BLOCK macro, it solves one of my perennial problems with Lispy languages (I believe I have ranted about this on HN too). The best I could come up with was something that required reimplementing defun, etc.

And thanks for the "pass" tip for Python. I gave up using Python a few months ago, and ported all my Python scripts to C and ObjC because I just couldn't handle indentation bugs after every refactor. Never realised the solution could be this simple.
