Well, both my point and Jim's was that trying to compile and run the
code would help to expose such silliness.

In the case at hand, there's another consideration: the examples are
large and are (I believe) intended as working skeletons for real code
development.  They'd be a lot more useful for that purpose if they were
available as actual contrib modules.  C code that's been hacked until
it passes for SGML isn't compilable.
