Very much agreed here. To me it’s programming with limited scope, simple well defined goals, and no side effects.

Pretty much everything programming isn’t in the real world.

And feedback too. In the real world your program don't tell you if they're correct, or efficient without a lot of extra work.

It's also much easier to find a solution if you know there is a good solution to be found.
