I have one problem with this article:

Lifetimes are hard.

That's true, but it's true for all non-gc languages, and a problem for gc'd ones too.

Lifetimes are not, in fact, hard, given a bit of library and language support. Persuading your compiler that you are right about them might be hard (even when you are).
