The `codecs.register` approach is interesting. I hope Ruby has something similar. Unfortunately I could not find such thing in Ruby.

Yup that's the point of my submission, too bad HN edited my title so it looks like a boring trick. It allows you to transform your code without significant speed loss.

Think of possibilities like

# coding: JIT

or

# coding: inline-C

etc.

The typical way to do that is to reuse the interpreter infrastructure. This hack could be done with the ast:

AST is cool, but you have to comply with Python's syntax.

the coding way you can invent any wild syntax.

I guess my first approach to that would not involve overloading the import statement.
