I'm not sure how documented the behaviour you describe is, but the trailing double colons have another use. Consider the following:

use 5.010;

{
   package Foo;
   sub new { bless [] }
   sub Bar { 'Quux' }
}
{
   package Foo::Bar;
   sub new { bless [] }
}
{
   package Quux;
   sub new { bless [] }
}

my $object1 = Foo::Bar::->new;
say ref $object1;   # says "Foo::Bar"

my $object2 = Foo::Bar->new;
say ref $object2;   # says "Quux"
