That would be excellent.

Literate programming

There are two programs involved.

Weave creates a nicely formatted, publishable version in TeX, where code
segments and their commentary appear together, with cross-references to
the context of the code. These segments can thus appear in a sequence that
develops logically for humans.

Tangle removes the commentary and puts the code fragments into the
indicated order as source code, ready for compilation or interpretation.
Knuth also created a TeX style for literate programming with the
appropriate markup entities and macros.

APL originated as Iverson Notation, a language for people to use when
talking about computers and algorithms, and was not implemented for
several years. Of course, most people are not willing to learn that much
math. There is, however, an APL version of Literate Programming.
