I think this technique also came up on Boost last year. I first applied
and presented it ~1995, and I'm sure there must be examples from before
that, so I guess it's been around a while.

I was about to write a column for C++ Report on the very same topic when
Herb fortunately pointed out that Bjarne had already done so! However,
if anyone's interested I have a current paper (submitted to EuroPLoP)
that includes coverage of this idiom.
