Subject: Parameter name reflection

If I declare

def foo(a, b)
end

What code should I use to find the names of the parameters?
I only see these methods available on a Method object.
["[]", "arity", "call", "to_proc", "unbind"]

For instance in PHP I could do this

function foo($a, $b) { }
$ref = new ReflectionFunction('foo')
$ref->getParameters()[0]->getName(); // a
$ref->getParameters()[1]->getName(); // b
