Yup. I am bemused by the efforts put into analyzing loops so that they can (by 
the compiler) be re-written into a higher level construct, and then the higher 
level construct is compiled.

It just is backwards what the compiler should be doing. The high level construct 
is what the programmer should be writing. It shouldn't be something the compiler 
reconstructs from low level source code.
