Possibly unbounded variable not found

[alonme]

Bug description

text = input()

if text == "testing":
    unbounded = True

print(unbounded)

For some reason unbounded isn't caught by E0601 (or other rule.. but it should be caught by something...)

If a simpler condition is used the problem doesn't happen

if 1 == 2:
    unbounded = True

print(unbounded)

Thanks for the report. Will be marking as duplicate of #1727. pylint has more reusable utilities to facilitate implementing this now, in 2023, than when it was first proposed 👍
