"Compile time" checking?

Since Python does not use manifest typing, there's not much you can do about
this, but typeless languages like this are great if you're using a process
that finds the errors the compiler would otherwise find. I'm referring, of
course, to Test Driven Development (TDD).
If you do TDD, you won't miss compile-time checking much. In fact, the extra
kruft that manifest typing requires is an annoying burden when doing TDD, so
Python is a breath of fresh air in this regard.
