I guess I would recommend perhaps LISP, FORTRAN and APL if you wanted to pick old time languages. More recently you might want to take a look at Ruby and Haskell, to pick a functional language, and COBOL, which has some interesting ideas in it you won't find in some of the other languages. -- Guy Steele Notice that he lists COBOL as a language to learn. I've always found Dijkstra to be a little over the top (often the only way to get people to listen), and Steele more pragmatic. http://www.infoq.com/interviews/Programming-Languages-Guy-Steele http://www.infoq.com/interviews/Programming-Languages-Guy-St...
