Method parameter modifiers: out and ref

Ruby IronRuby
1

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?

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]
