1- Pensou, não é XGH.
XGH não pensa, faz a primeira coisa que vem à mente. Não existe
segunda opção, a única opção é a mais rápida.
2- Existem 3 formas de se resolver um problema, a correta, a errada e
a XGH, que é igual à errada, só que mais rápida.

solidsnack / namedtuple.py
Last active August 29, 2015 14:28
Namedtuple annotation for Python -- derive namedtuple definition from the signature of __init__()!
"""Namedtuple annotation.
Creates a namedtuple out of a class, based on the signature of that class's
__init__ function. Defaults are respected. After namedtuple's initializer is
run, the original __init__ is run as well, allowing one to assign synthetic
parameters and internal book-keeping variables. (Note that the original
__init__ may not assign to the variables in its signature, because these
variables are made immutable by namedtuple).
The class must not have varargs or keyword args.
