At times like this I turn to the ancient poetry form, IDL-ku.  Like
the haiku it must adhere to the terse 5-7-5 syllable structure, but
must also be a compileable IDL program.  The equals sign, "=", can
either be silent or short-hand for the one-syllable, "is."

yes, _ref_extra = $
useful, NOT a, figment (from)
JDs, imagination

arrays, alter (shape)
at, unexpected, moments;
remember, reform (them)

display: the image;
for robust=results, please do $
use, imdisp OR plotimage

Nuggets of wisdom from the ages...  Not answers to every question, but
then again we must leave some mystery for the new people.
