Revision

I find myself revising both the code and document of literate programs more than ordinary (illiterate :P) programs. I think it's because of the expository nature of literate programs, since revision is unavoidable for good expositions.

Also I find myself writing deeply-nested code in my current CWEB program. I hope it's because of the ad hoc nature of this program, since deep-nesting is hard to read even if CWEB can break them into not-so-deeply-nested sections.
