Changes introduced in 1.3.1.post0.dev21 break build

In my test code I mock user input to simulate interactive console interaction.
Since above mentioned version, the tests jump into interactive mode instead of being mocked (vs. `.dev20`, which I just confirmed to still work).

The code in question is thus:
```
input builtins
def mockInput(datas:str[], func) -> Any:
with mock.patch("builtins.input", side_effect = datas): return func()
```
being used in the test cases as
```
mockInput(["t"], () -> sos.update("mod", ["--ask-lines"]))
```

Any changes in the coconut imports that lead to that error?
