In the following Groovy snippet, I attempt to replace both the hashCode and toString methods
String.metaClass.toString = {-> "override" }
String.metaClass.hashCode = {-> 22 }
But when I test it out, only the replacement of hashCode works
String s = "foo"
println s.hashCode() // prints 22
println s.toString() // prints "foo"
Is toString somehow a special case (possibly for security reasons)?
