Which problem does that solve, the problem of having working code that does something useful?

Blockquoth the root post:

The problem is that I just want to throw them all away, start from scratch (on paper), and rewrite them.

So, that problem.

Rewrite the code, develop a nice, shiny, new interface for it. Clean up the internals, hell, maybe even write it in a more maintainable language (like ASM </troll> ;-P).

Really, you'll feel much better :).
