A profound part? Maybe not. However, I noticed yesterday that a provisioning tool I wrote was blowing because I was assigning by mistake an empty string coming from a CSV instead of a None value to an integer field in an sqlalchemy model. That's a bug a static type system would have found.

Almost every exception a Python program ever throws is or can be made a type error (or otherwise statically caught) in Haskell and similar languages. A type error is not the same thing as a TypeError.

When someone dumps a large Python codebase on you, it is significantly harder to figure out how it works than with a statically typed program, since it is harder to figure out what types to use and are returned by any given function call.
