If you can't do that, then you're not going to get far understanding
*any* program.  The (alleged) added effort in understanding this construct
is surely miniscule in the context of understanding a whole program.

I would have thought that it's common enough to be regarded as a
standard idiom itself.  At least, everyone who reads this newsgroup
should by now be quite sufficiently familiar with it!
