I want to increment it, so I'd say a += 8. Now if this is a parsing app, the increment may happen everywhere -- so I'd write a function to do it if I worry about it being initialized before. Is there any operator/expression level support for what in ruby looks like a ||= 0 -- http://mail.python.org/mailman/listinfo/python-list
