DGD has had something similar in the past, but the solution was abandoned
after it turned out to have more drawbacks than advantages (see the
Changelog file for details).  the `<' solution I consider to be a typical
example of the eyesore-causing technological progress common in Amylaar's
driver :)

I have no such change planned, but expect the code optimizer to better
optimize such code in the future.
