인수

closure: The anonymous functions to bind.
newthis: The object to which the given anonymous function should be bound, or NULL for the closure to be unbound.
newscope: The class scope to which associate the closure is to be associated, or 'static' to keep the current one. If an object is given, the type of the object will be used instead. This determines the visibility of protected and private methods of the bound object. It is not allowed to pass (an object of) an internal class as this parameter.
