Extension methodsare only used when the namespace containing them has been imported, andare based on the static type of the object they are being called on.They also have no access to the object's private members.Python doesn't have static types and doesn't have private members, andusing this would make a real modification to the type the method isbeing added to rather than relying on namespaces being imported, sothere would be fewer barriers to "use this for everything" than "useextension methods for everything in C#".
