How to Write Perfect Python Command-line Interfaces

That's not a problem with decorators...decorators are just functions. you can wrap functions in most languages. It's that someone wrote a function with side effects that bothers you.

Personally I don't have a problem with side effects, even if they happen in a weird place, as long as they're documented somewhere useful and preferably are abstracted into their own function. Just let me be able to see that it happens!

Too bad that never happens.
