Yeah, but you should use something like JITWatch as well, not all news turn into heap allocations. Unfortunately value types are years away, if they ever land.

If you can prove that that a particular value never escapes the scope, it may be possible to allocate it on the stack instead which also reduces the amount of garbage collection needed later.

  Correct. I had to make it concise for the joke, though. :)
