[PATCH] WIP Fix for temporary destructors in conditionals

[Jordan Rose]

  I'm an idiot. :-) Okay, I believe you there, but again I want to see what happens when environment cleaning is actually triggered.

  What's the destructor look like for "`A arr[2]`"? I believe that should already be handled, even if it's just a very early special case to bail out. If so, you should be able to do something similar for temporary destructors.
