New submission from Ryan Fox:
If a variable 'x' exists in the global or local scope, and a function (also
defined in the same scope as 'x', or lower) refers only to a member named 'x'
of an object, inspect.getclosurevars will include a reference to the variable,
rather than the member.
Okay, that's kind of confusing to describe, so here's a small example in code
form:
import inspect
class Foo:
x = int()
x = 1
f = Foo()
assert(f.x != x)
func = lambda: f.x == 0
assert(func())
cv = inspect.getclosurevars(func)
assert(cv.globals['f'] == f)
assert(cv.globals.get('x') != x) # <--- Assertion fails
It is expected that 'x' would not exist in cv.globals, since func does not
refer to it. Also, there should be a 'f.x' included somewhere in the
ClosureVariables object returned.
