[Python-ideas] Does jargon make learning more difficult?

[David Mertz]

This isn't trying to snipe. I have written the exact same unnecessary
circumlocution in my own code hundreds of times. Hopefully most of them
simplified before release, but I'm sure not all. And I "wrote the book", as
one says, _Functional Programming in Python_.

Functions as sounds is a powerful but counterintuitive concept.
