The problem is that _pyio.open doesn't behave exactly as io.open when it's used
to define a method:
---
#from io import open
from _pyio import open
class MyClass:
my_open = open
MyClass().my_open("document.txt", "w")
---
This code currently fails with a TypeError, whereas it works with io.open.
The problem is that I failed to find a way to create a function in Python which
behaves exactly as built-in functions like len() or io.open().
