the 'postfix:::' operator

[Jerry Gay]

that's postfix ::, as mentioned in the Names section of S02.

<snip>
There is no longer any special package hash such as %Foo::. Just
subscript the package object itself as a hash object, the key of which
is the variable name, including any sigil. The package object can be
derived from a type name by use of the :: postfix operator:

MyType::<$foo>
<snip>

i don't see it anywhere in S03. probably should be, if it indeed
exists, method postfix.
