AST transformation is nice but you can also have magic macros using `coding` hack. It could add arbitrary syntax to python

I'm a little confused where you are going with this. Could you elaborate a little? Its one thing for this to be possible using `coding`, but this is a macro builder available right now. Interpy just highlights the possibility of this, right? If there were a macro framework that used `coding` it would seem more relevant. Otherwise it looks like you're comparing apples and a knife. Am I missing something?

Does JSX-like template for Python count?

    # coding: pyxl
    print Hello {my_var}!
Combined with this, we can make Meteorjs-like applications in Python directly. Even AST transformation of backend DOM operations in Python directly rendered to Javascript to browser.
