Languages in which HOP is common provide all sorts of handy abbreviations
For example
-- Haskell half = (/2) recip = (1/) divide = (/)
And you probably don't bother to give these names
In Perl, you get to do
my $half = sub { $_[0] / 2 };
my $recip = sub { 1 / $_[0] };
my $divide = sub { my $num = shift; sub { $num / $_[0] } };
Or you get to insert these monstrosities inline
