There are six singleton pseudo-variables that act as reserved words: true,false, nil, self, super and thisContext. > Lisp: AFAIK, there are no truly reserved words in Lisp, only predefined > functions. (??) All Lisps have "special forms" which are evaluated uniquely and differently from function application and are therefore reserved words by another name. For example, Clojure has def, if, do, let, var, quote, fn, loop, recur, throw, try, monitor-enter, monitor-exit, dot, new and set!. > Python: 31 > Ruby: 38 > Tcl: Same analysis as for Lisp I believe.

I don't think it really tells you that much. Possibly that a little superficial complexity through syntactic sugar can make your language a lot more human-friendly, but that it's possible to go too far and end up like C++.
