Been here since the days of scheme at least http://docs.racket-lang.org/guide/eval.html#%28part._namespaces%29 For the record lisp was conceptualized in the late 50s and implemented by 1960. By the 80s it was widely regarded as the premier AI language but it was also clear to users that the scoping rules were terribly wrong. So a number of the then lisps coalesced and re-separated into 2 major dialects -- scheme and common lisp. I expect it -- 2 argument eval -- goes all the way back to the earliest lisp but Ive not access to the history. -- https://mail.python.org/mailman/listinfo/python-list
