Just reading up on Pike...

.... and this just jumped out at me:

class Foo {
        private string|int bar;
        static create(string|int newBar) {
                bar = newBar;
        }
}

In other words, as I understand it, you can type the variable bar as 
either an int or a string.

Aside from simply, "my $bar;", will we be able to repeat this behavior 
in Perl6 programs?

Let me guess, though, this is one of those instances where I should have 
read A1..5 and E1..4 more closely.  :-)
