break! seems to be broken. Executing the example in the REPL leads to this:

>>> ok = for x in range 10 =>
...   if x == 5 => break!
...   print x # 0..4
... print ok  # False

Python version is Python 3.6.9 and I've used the -b option to create a bundle for that to get rid of the warning I got at startup.
