As I already mentioned, the HHVM implementation is hackish, but the
reception around Facebook about the feature itself was SUPER positive.
Particularly when paired with collections.  $someDict->map($v =3D=3D> $v *
2)->filter($v =3D=3D> $v % 3); just reads way cleaner than the old
expressions.

FWIW, (with my HHVM hat on) we'd also discussed that we wouldn't be
too bothered if PHP went with a different syntax as it would ease
pressure to match behavior on a feature that's already widely deployed
internally.  So don't worry about picking a symbol based on what Hack
uses.  Pick what makes sense for PHP.  For my part, I care FAR more
that we get short closures than what gymnastics my fingers have to
partake.
