Been here since the days of scheme at least
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.
