What is the standard you're talking about? Common Lisp? Scheme? Clojure? Emacs Lisp?
Hy looks like it borrows heavily from Clojure, which borrows from Common Lisp in terms of names, but they are both different languages and so they differ. About the only objectionable name I found in Hy is `assoc`, which I'd expect to return the value with given key and not set it.
And CLOS is quite a good object system, actually. I somehow missed how it's implemented in Hy, but multiple dispatch would be cute in Python.
