There's a barrier of entry for the army of people who use Python but are not (and often have no interest in being) engineers/developers/programmers.

This is the modern equivalent of building key components in Visual C++ for use by Visual Basic people; it kept the unwashed masses away from things they could break.

I think that this is probably the only way you're ever going to fix the horrific experience of using Python in anger. Which is a good thing, Python's a great little language which is let down by being built on sand.
