I've never used cl-opengl, but the usual nameing convention for lisp names is as follows: name-with-multiple-words *global-variable* so GLOBAL_VARIABLE and NameWithMultipleWords or name_with_multiple_words are easy to figure out. Any body who has used lisp for more than a few days knows how to name things, and since the combinations of naming schemes in C is finite, figuring this out is close to common sense. so glLoadIdentity() in lisp is (gl:load-identity). Happy Hacking!
