Hi There,
I am not sure if my RoleType @array; is correct, or if there is a better
way to declare such an array. But I find the error that is happening
when there are no elements in the array confusing on the first sight. It
took me a while to realize that my array was empty and therefore it
"means" the class/role itself.
> perl6 -e 'role Foo {method n{...}}; class Bar does Foo {method
n{"n"}}; my Foo@a = (); @a.push: Bar.new; say @a[0].n'
n
> perl6 -e 'role Foo {method n{...}}; class Bar does Foo {method
n{"n"}}; my Foo@a = (); say @a[0].n'
Method 'n' must be implemented by Foo because it is required by a role

No such method 'n' for invocant of type 'Any'
