You are doing something sneaky in *any* language because if anyone else
defines newMethod in any other module anywhere in the system you'll
overwrite each other. Classes are more or less global variables and so
are their methods.
Python would probably not have first-class syntax to do this until there
were a way to do it that scaled well to large programs written by people
who do not necessarily communicate with each other.
