There are many examples where implementations had mistakes that would have
been easier to recognize if the notation in the code and the documentation
were more similar. One approach that has been used ("literate
programming") relies on a source file that uses typesetting markup and
can be processed to produce either a document or conventional program
sources. Some such systems allow use of greek symbols in the program
source, and replace them with conventional names when the sources are
extracted. This has been been done for C and Fortran (the project, fweb,
like many legacy Fortran codes, is, no longer being maintained).

I have used literate programming tools with IDL, but only in a form where
the source fragments in the documentation are assembled into the actual
source files when the document is formatted. See:

<http://www.cse.ohio-state.edu/~gurari/tpf/html/LitProg.html>

for a simple system based on TeX. This seems to be a good compromise
between simplicity (so it doesn't require a big maintenance effort) and
functionality.
