I agree with Paul's sentiment. We do not need to bless just one way of
writing scripts. Code review or organization style guides, sure. But not at
language level.
I also write scripts with no explicit __main__. But I rarely name them as
.py. In the style of Unix commands, they have no extension, but have a
pound-bang at the start. This has the side effect of making them much less
straightforward to import at all.
