list -           the original listparameterType -  the resulting array type
methods -  the methods to choose fromWarning: this method does not choose properly if multiple methods with the same distance are encountered
methods -  the methods to choose from
list -    a list of MetaMethodsmethod -  the MetaMethod of interestConverts a String into a standard property name.
prop -  the original nameparam instance array to the type array
args -  the argumentsSets the metaclass for an object, by delegating to the appropriate DefaultGroovyMethods helper method. This method was introduced as a breaking change in 2.0 to solve rare cases of stack overflow. See GROOVY-5285. The method is named doSetMetaClass in order to prevent misuses. Do not use this method directly unless you know what you do.
self -  the object for which to set the metaclassmc -  the metaclassReturns a callable object for the given method name on the object. The object acts like a Closure in that it can be called, like a closure and passed around - though really it's a method pointer, not a closure per se.
object -      the object containing the methodmethodName -  the method of interest
