Y'know, one feature I've always wanted is the equivalent of

how your
code was translated, and whether it matches what you *think*
it does.
This would also be invaluable for debugging, as then it will
map to the
assembly code much better, which will help you trace where
things went
wrong.
I do this with a debug build of the compiler. Using --b will
give you the expression trees sent to the back end.
Why is this not a feature in the release? Seems like a very
useful feature to have...
