They are just like out parameters that have input value as well.
public class C {
public int foo(ref int bar) { bar++; return 3; }
}
p C.new.foo(1) # => [3, 2]

Subject: [Ironruby-core] Method parameter modifiers: out and ref
I am trying to work with a .NET lib that uses ref modifiers on some method
params and am not sure how to work with them from Ruby. I know with out
modifiers that those parameters become part of the return values, but what can
I do with ref parameters from Ruby?
