Aside from the name question (I'd maybe like first-available()?) the
question arises, what would be the difference between
first-defined(($a,$b,$c)) and head(($a,$b,$c)) or ($a,$b,$c) => head() as
the case may be?
That's a good point! I had not thought of head() in this context.
My inclination is that while
head(('','thing','widget'))
and
('','thing','widget')[1]
both return '', first-available(('','thing','widget')) ought to return 'thing',
but I also feel my toes starting to extend out over an abyss.
