I think you misunderstood. I'm not talking about Python throwing errors about the types of my variables. Like I said, I'm already quite comfortable with Python.

I think you misunderstood. I'm not talking about Python throwing errors about the types of my variables. Like I said, I'm already quite comfortable with Python. I'm talking about Django failing to check whether my Django-specific code (e.g., templates) is valid, so that Python gives me an error message that appears to originate inside the Django codebase, instead of Django giving me an error message about the syntax of my template. I've only briefly tried CakePHP, but IIRC its error handling was excellent.
