How do you add a method to an existing class in Perl 6?

Question

The Int class has a method is_prime, so I figured, just for giggles, I\'d like to add some other methods to Int for some of my hobby projects that do n

Answer 1

You can also simply call a sub like a method by including the & sygil:

sub is-even(Int $n) { $n %% 2 }
say 4.&is-even;  # True

It's just syntactic sugar, of course, but I've done it a few times when it looked more readable than simply calling the sub.

(I know you're “not looking for workarounds or alternate solutions”, but you posted some yourself, so I thought, why not?)
