thank you for this. The differences between these two methods eseems like one of those instances where actually knowing the subtle differences could save you from a serious headache.

I think i understand the logic of what's going on here, but how does the .__instance work? I can't seem to find any documentation on it.

yeah I had a similar experience. Much simpler than I first thought.

This one gave me way more trouble that it ought to have.

it would have been nice to know that you do not need to create the MyObject 'class'. I kept defining my own and it was throwing off the tests because I didn't give it any methods

this was a good one. I almost entirely over-thought it. Nice Kata.

this is a clever way to solve (especially in one line). Bit tricky to read though; nice work!

I don't mind having to essentially re-type the similar functions. For me it just helps re-enforce the concept and help commit important methods (and how to use them) to memory.
