I feel the exact same way. Python gave me so much flexibility and escape hatches when I did dumb design things as a novice. Now as a veteran I just want a boring, strong static language with clear boundaries and behavioural expectations
I just always found it nice as a prototyping language. If you have an idea of how you want to do something or solve some problem, create a working prototype in python.
Then create a more polished version in another language.
I don't think terseness is the issue. It's the fact that it lets you do anything, even if it's a terrible idea. `__subclasses__` is my favourite example of that.
