Right. The x/y syntax is used both for namespaces and static methods,
and namespaces win. Here you have both a namespace and a classname
called my.hello. So, for calling gen-class'ed static methods, you'll
need to use (. classname static-method) for now.
I'm not sure this is really an issue, but I'm open to feedback.
