List methods

You can get a list of an object's methods using .^methods, which is part of the Meta Object Protocol.

Each is represented as a Method object that contains a bunch of info:

class Foo {
    method foo ($x)      { }
    method bar ($x, $y)  { }
    method baz ($x, $y?) { }
}

my $object = Foo.new;

for $object.^methods {
    say join ", ", .name, .arity, .count, .signature.gist
}

Output:

foo, 2, 2, (Foo $: $x, *%_)
bar, 3, 3, (Foo $: $x, $y, *%_)
baz, 2, 3, (Foo $: $x, $y?, *%_)
