Personally I find Common Lisp in some cases slightly uglier, but clearer. (define foo (make-foo)) What is it? A function or a non-function? I prefer the Common Lisp version: (defvar *foo* (make-foo) "*foo* is the current input/output foo object.") It's clear that DEFVAR usually defines a variable and not a function. Bonus: we can document the thing in a standard way. For functions I would define a define macro. (define foo (make-foo) "foo is a function with two arguments of type bar, it returns ..." (ftype (function (bar bar) baz)) Which would expand into a (setf fdefinition), a type declaration and setting the documentation. I prefer the uglier, but better standardized and slightly more practical language.
