> Who writes python this way? People learning the language or learning programming, something Python is supposed to be good for and is widely used for. Also, casual and intermittent users of Python, who might not hold all the details in their head because they work in multiple different languages. These categories would encapsulate the majority of Python users in practice, and all of them end up "QA testing" the language unintentionally and wasting time and effort figuring out inscrutable problems. A better designed language could prevent a lot of these abuses, give informative error messages, or at the least warnings. These are not inevitable results of language flexibility, but in many cases just the result of poor design that got patched up imperfectly over time - which is understandable given Python's history, but doesn't make the problems go away.
