The SmallScript Common Dynamic Language Runtime (CDLR) System is a rich multi-paradigm dynamic and scripting language architecture. It includes S# as its primary language, a superset/dialect of classic Smalltalk-98. Generally referred to as the "S#" language. (See Informal Language Comparison Chart).

I never did get SmallTalk, but it's nice to know that laguages are added all the time.
