It is??!?  WOW!  I wonder if I am due some back royalties or
something for that.

The idea of loop-and-a-half is not my invention, nor is it my
attempt to contribute to what structured programming should be.
Rather it was given an example that I hoped would explain and
elucidate the essence of what structured programming already is,
as detailed in Dijkstra's monograph.  Regrettably that hope
appears not to have been fulfilled.
