You've got two variables called @anyvar in that code, and they have no
relation to each other.

The first one is an instance variable belonging to the module Mod
(that is, the actual object Mod). The second one represents an
instance variable that will belong to each object that executes the
func method.

So the @anyvar = 10 line is serving no purpose.
