Bug Report

Same as title. The code example below shows a function being properly typed.

To Reproduce
This code produces the bug.

class WorkedAsExpected:
    ...

def deco(a: Any) -> WorkedAsExpected:
    return WorkedAsExpected()

@deco
def function_test() -> None:
    ...

@deco
class ClassTest:
    ...

reveal_type(function_test)  # Revealed type is "test.WorkedAsExpected"
reveal_type(ClassTest)  # Revealed type is "def () -> test.ClassTest"

print(type(function_test))  # <class '__main__.WorkedAsExpected'>
print(type(ClassTest))  #<class '__main__.WorkedAsExpected'>

Expected Behavior

reveal_type should be the same type for the function and class examples. The function example is the expected result.
