Have a look at Io at http://www.iolanguage.com/
or Lisaac at: https://gna.org/projects/isaac/
or Self at: http://self.sourceforge.net/
or Sather (now absolutly forgotten)
or Eiffel http://www.eiffel.com
Why here are a few reasons. Io is absolutly minimalistic and does not even have "control flow elements" as syntacit entities. Lisaad is a follow-up to Eiffel with many simplifications AFAIKT. Self is a followup to Smalltalk and Io has taken quite alot from Self also. The base thing is that the distinction between Class and Object has been given up. Sather is a anwer to Eiffel with a few other rules and better support for functional programming (right from the start).
And Eiffel is definitly a hallmark for statically typed OO-languages. Eiffel was the first langauge whith support for Design by contract, generics (aka templates) and one of the best ways to handle inheritance. It was and is one of the simpler languages still. I for my part found the best libraries for Eiffel.....
It's creator just has one problem, he did not accept other contributions to the OO field.....
