MetaObjectProtocol
Returns an object satisfying Groovy truth if the implementing MetaClass responds to a method with the given name and arguments types.
Note that this method's return value is based on realised methods and does not take into account objects or classes that implement invokeMethod or methodMissing
This method is "safe" in that it will always return a value and never throw an exception
