I like P6 syntax and semantic more them P5.<p>My only one problem about P6 is the fact they dropped the effort of having the specification so others can implement the language too. Looks like they prefer a conformance test instead of a formal&#x2F;complete specification.<p>While that is perfect fine, I would say having both the test and the spec is even better, for those trying to learn and implement the language.<p>A good, formal and complete specification will make my learning process much better, IMHO.
