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. ~jerry
