public class SecondParam extends PickAnyArgumentHint

A hint used to instruct the type checker to pick the second parameter type. For example:

`public <T,U> def doWith(T first, U second, @ClosureParams(SecondParam.class) Closure c) { c.call(src); }`

This class has several inner classes that also helps picking generic argument types instead of the parameter type.
