New submission from Matthias Bussonnier:
Raymond Hettinger reported during PyCon Canada 2016 Keynote (~20m30 sec)
that unbound local error message was inaccurate, it state that :
> local variable 'xxx' referenced before assignment
Though it can be assigned and deleted.
for a toy example:
def foo():
x = 1
del x
print(x)
foo()
Do the same for free variable.
def multiplier(n):
def multiply(x):
return x * n
del n
return multiply
The error message can be improved by adding "or got deleted".
