Prof. Knuth came up with an interesting solution to that -- in the
process, inventing (or maturing) the concept of "literate programming".

Perhaps it's not well known that his most widely used programs (e.g.
TeX) were written in something VERY close to standard Pascal
(preprocessing aside). The translation to C (as required by certain
platforms) was mechanical.
