That's a function I've written a number of times, but it does evaluate
both yes and no, whether needed or not - a fine idiom for picking one
of two strings or numbers, etc.
I call it 'pseudo' because it would be part of the grammar - only way
one could get that late evaluation. At least there would be no
arguments about precedence...
