There's no convenient way to do that in Python.

Different languages have different degrees of syntax mutability.
Lisp is at one end of the scale.  At the other end, there's Java.
Python and Ruby are both somewhere in the middle, with Python taking
a conservative approach and Ruby a more liberal one.

In Python, if you want to wrap some code, wrap it in a function.
