interesting thread, but doesn't really answer my question.
as a human, it is obvious from that snippet alone that the variable x is never read. therefore, unless `classes.ElementAt(i).Name` has some side effect, the entire loop could be replaced with a no-op without changing the program semantics.
so my question isn't about GC behavior at all. I expect the entire loop to be optimized away (no code emitted). why doesn't c# make this optimization? is it something subtle about how properties work, or does the compiler not attempt these optimizations in general?
