Creates a new Expando. The optional name is only used for debugging purposes and creating two different (non-const) Expandos with the same name yields two Expandos that work on different properties of the objects they are used on.

const Expando([String name]);

Sets the value of this Expando's property on the given object. Properties can effectively be removed again by setting their value to null.

void operator []=(Object object, T value);

Gets the value of this Expando's property on the given object. If the object hasn't been expanded, the method returns null.

T operator [](Object object);
