Hi people,

I wrote this decorator: https://gist.github.com/yasar11732/7163528

When this code executes:

    @debugging
    def myfunc(a, b, c, d = 48):
        a = 129
        return a + b

    print myfunc(12,15,17)

This is printed:

    function myfunc called
    a 12
    c 17
    b 15
    d 48
    assigned new value to a: 129
    returning 144
   144

I think I can be used instead of inserting and deleting print
statements when trying to see what is
passed to a function and what is assingned to what etc. I think it can
be helpful during debugging.

It works by rewriting ast of the function and inserting print nodes in it.

What do you think?
