What is the Perl6 equivalent of the perl 5 "::"?

It's the same... but unlike Perl 5, there is a difference between subs
and methods, and subs are lexical by default (that is, they behave as if
defined "my sub ..." --- which syntax is legal in Perl 6 (and I think in
sufficiently recent perl 5 if you specify a minimum version in your
script)). For a sub to be callable that way, it must explicitly be
defined as "our sub ...".
Although you will run into another issue because you have whitespace
before the "(", so it will be called with one parameter that is a
2-element list.

Could not find symbol '&Which'

Line 35 works, but line 36 does not.
I am stumped
