Apologies, I thought you were simply proposing the following:
interface Countable
{
function count(): int;
}
But you're actually proposing the following as well?
interface Arraylike extends Iterator, Countable
{
}
I can see the use of an interface which combines Iterator and Countable,
but not Countable on its own.
