Less-ness

Since ANF and DOT are just convenience representations, I am removing them by 'fusing' the introduction and removal of DOT. I also simplified the throwing of exceptions: explicit code has its merits, since it generates readable output, but the overall aim is a minimal, but flexible, fast compiler.

HD Failure

Duh, disk crashed. Which, given headaches and the time I have left, ain't good. Fortunately, saved my compiler to USB just on time. I lost the test scripts and all other stuff I was developing - I usually work on multiple projects. Could have been worse, though, I guess... Moved it to one of my other laptops, it compiles again.
