I miss it, but very rarely. It's nice in a binary search,
and it's nice in heapsort, but I can't recall other contexts
that made me wish it were still around.
An ironic oddity: In the numerical applications for which
FORTRAN is justly famous, the three-way IF is almost never the
right thing to use! You don't want "negative,zero,positive"
but "noticeably negative,close to zero,noticeably positive."
