However today I'd decided to write down my long waiting ideas on language modularization and unit testability.<BR/><BR/>The text may not be worth anybody's attention but since I feel it may be relevant, here's the link<BR/>http://atagunov.blogspot.com/2008/03/singleton-free-jre.htmlAnton Tagunovhttp://www.blogger.com/profile/04903035827978774750noreply@blogger.comtag:blogger.com,1999:blog-17087850.post-77640374231979414142008-03-21T15:00:00.000-04:002008-03-21T15:00:00.000-04:00Factor singletons don't have state, they're just symbols which can be dispatched on.
