There's a nice introduction here, which is aimed at experienced functional programmers: http://shenlanguage.org/documentation/Tutorials/Shen-in-15min.htm http://shenlanguage.org/documentation/Tutorials/Shen-in-15mi... Shen appears to be a strongly-typed functional language with a Lisp-like syntax. It supports pattern matching: (define sum-list [] -> 0 [H|T] -> (+ H (sum-list T))) ...partial application: (* 3) ; returns (/. X (* 3 X)) ...as well as macros that can alias function names: (defmacro logmacro [log N] -> [log N 10]) There's also an embedded "Prolog" implemenation, though I don't know how complete it might be: http://shenlanguage.org/documentation/prolog.htm http://shenlanguage.org/documentation/prolog.htm However, there doesn't appear to be an object system or a monad library, and the "lazy evaluation" system uses a typical promise/force approach, which every Scheme has had for decades. So Shen may not be well-suited to the kind of fun tricks available in Haskell and (to a certain extent) Scala. Still, it's definitely an interesting language.
