Consider:
my $foo of Num where { 0 <= $^n < 10 };
Is the following also valid?
my $foo where { 0 <= $^n < 10 };
Or does that have to be like this?
my $foo of Scalar where { 0 <= $^n < 10 };
And can $_ be used instead of $^n?

I don't see why not. The main place C will be useful is in
multimethods, and I see that as a reasonable shorthand:
multi sub foo(Bar $x, $y w

I do?
Can't say I understand well when a topic is implicitly defined and when
not. It's obvious for for-loops and given, but everything else is
blurry to me.
