I like the suggested syntax. The only drawback I see is that it inhibits =
the future addition of union types for closures:

=C2=A0 =C2=A0 =7Cint =7C float =24x=7C =3D> =24x

Adding parentheses of course resolves the issue but looks a bit awkward:

=C2=A0 =C2=A0 =7C(int =7C float) =24x=7C =3D> =24x

Apart from that I have nothing to complain about. I'd be happy either way=
.
