Only allowing spaces was a good decision. It was supposedly inspired by a quote from Guido bin Rossum that if he could redo it he’d only allow spaces in Python, or something along those lines. It eliminates lots of issues mixing code that has tabs or spaces like in Python. I’ve never had to worry about a lingering tab.
