We're very open to tweaking the keywords.  I can see the argument for "a=
s" being a little misleading in PHP's case.  Though I'd prefer to have t=
he EXPR first and VAR second, whatever the keyword is.

Another potential we thought of: Just plain =3D>.  It already doesn't im=
ply equals, would have no keyword breaks, and is still only 2 characters.

using (new SomeManager() =3D> $someResource) {
  // ...
}

Thoughts?
