For cleaner code, write ugly code

Author's premise: Intentionally writing extremely bad prototyping code motivates one to later clean it up and thus produce better code.

I strongly advise anyone considering this to first try rapidly prototyping code that is as good as you can do quickly. Over time, the quality of your prototyping code should improve and require less cleaning to achieve a high quality result. You should not have to intentionally create reasons to clean up code. The reasons will appear naturally enough.
