�Zgddd�Zdd�ZdS)a:Fixer for function definitions with tuple parameters.

def func(((a, b), c), d):
    ...

    ->

def func(x, d):
    ((a, b), c) = x
    ...

It will also support lambdas:

    lambda (x, y): x + y -> lambda t: t[0] + t[1]

    # The parens are a syntax error in Python 3
    lambda (x): x + y -> lambda x: x + y
