I'm not sure where "class.var" comes from... var is an instance
variable of A objects, it looks like, not of A (unless you meant that
local: clause to come after the method definition?) and in any case
you haven't defined a method called 'var', just a variable.

Also, how would you differentiate between the instance variable var
and a local variable (or method) called var?

(Mind you, my basic feeling about 'local' is that I would dislike it
:-)  Nonetheless I'm curious how you would see it playing out.)
