pylint #77982 False positive: undefined variable error [validation pending]

the following snippet generates a false E0602:
E: 6,11:dummy_function: Undefined variable 'a'

# a decorator for testing purposes
def f(func):
return func

@f([dict(a=a) for a in range(10)])
def dummy_function():

It seems pylint has problems if a list comprehension is part of a decorator argument.
