Does the unwrapping process outlined in this course feel a bit ugly?

My instinct would be to continually try and create an extra function to unwrap the thing.

Yes, the fact that there are 16 questions associated with this one video/lesson seems to indicate that others had some issues with the way Amit tried to do things as well.

Personally I think it's one of those "I'm just using this as a teaching example,

but you probably won't be doing anything like this in a production environment"

sort of things.

Here's some links to other related Treehouse threads

that had alternative code to what Amit was using:

https://teamtreehouse.com/community/would-the-following-code-also-work-2

I really wish there was a way that students could upload "alternative approach" working code

as a zip and attach it to specific videos/lessons.
