These kind of problems can be solved or avoided altogether by a decent editor.
print("foo")
# x is false for the problem
if x:
do_something()
print("bar")
> never had this problem, well, some people do.
Neophytes also have a lot of problems with matching braces, neither is a panacea to those folks. But one is easier to read and type for everyone else, for years to come.
If the function is longer or their are a couple of additional levels of indentation, and it isn't a print statement, but some additional logic, it is a hard problem to spot.
Still at some point one needs to be responsible for the code they write, braces or not. Braces are not a guaranteed solution either, if the author gives up complete responsibility.
Basically, this is a theoretical non-problem. The lack of braces pays back in readability every single day. Like +100 + -2, then complaining about the -2.
You'll also note that I've never claimed braces were better, I'm just trying to explain OP's pont.
You may not encounter it, but "Hey it works for me" is not a legitimate answer.
