New submission from Marco Buttu:
The locals() documentation [1] says that "Free variables are returned by
locals() when it is called in function blocks". A free variable inside a
function has a global scope, and in fact it is not returned by locals()::
>>> x = 33
>>> def foo():
... print(x)
... print(locals())
...
>>> foo()
33
{}
Maybe "function blocks" here means "closure"? Does the doc mean this?
>>> def foo():
... x = 33
... def moo():
... print(x)
... print(locals())
... return moo
...
>>> moo = foo()
>>> moo()
33
{'x': 33}
In that case, I think it is better to write "closures" instead of
"function blocks".
