WEB has little to do with portability; in fact Knuth relied heavily
on the existence of an OTHERWISE clause in CASE statements throughout
the TEX source, and that is not standard Pascal.  There is also debate
about whether WEB is really worthwhile; a couple of years ago in the
Programming Pearls column in CACM, Knuth contributed a WEB example
which Doug McIlroy really tore apart.

We should probably limit the code readability discussion to code
as it is prepared for a standard compiler, not a version requiring
preprocessing with some additional tool.
