Hi folks,

It's great to see all this discussion. I wanted to jump in to clarify one thing:

The point of setting tabs to spaces is that we had huge headaches in
the first several workshops because students would mix tabs and spaces
and get indentation errors. It's not about what the community prefers
cosmetically.
