array_unshift is no more a special case of array_merge than array_push, pa=
rticularly in the single-element case we're talking about here - it's reall=
y just the same operation at the other end of the array=2E=20

Since we have an extremely well-established array_push shorthand, so don't=
 need a new one, we could perhaps have "<" for "at start", and "-" for "pop=
":

$foo[] =3D $toPush;
$popped =3D $foo[-];
$foo[<] =3D $toUnshift;
$shifted =3D $foo[-<];

I'm not totally convinced it's necessary, but I don't completely hate it=
