if (foo):
bar()
hum()
I suppose with very good tests, you might be able to catch something like this, but it seems impossible to me how a PR reviewer might catch a "bug" like this and not just assume that it's intentional.
I understand if statements not having their own scope for simplicity's sake, but the fact that `with` blocks don't is simply mind-bobbling to me. ``` with open("text.txt", 'w') as f: f.write("hello world") f.write("hello world") # at least the handle was automatically closed so it will give an IO error ```
One example would be a timing context manager:
with Timer() as t:
…
print(t.runtime)
if foo:
bar()
