I also suggest presenting a more straightforward example of mapcar, without #. Perhaps the existing example would make a good illustration for #. [[User:Mdmi|Mdmi]] ([[User talk:Mdmi|talk]]) 21:04, 15 December 2019 (UTC)
== LISP first appeared in 1960
When did LISP first appear? Development began in 1958. The paper describing the design of LISP was published in April 1960. The first working implementation of LISP was written based on this 1960 paper (but we don't know the year).
In the FORTRAN page, development began in 1953, a draft specification was published 1954, the official manual was published in 1956, and the completed compiler was released in 1957. Wikipedia says that FORTRAN first appeared in 1957.
Based on how the FORTRAN article is written, it is consistent to say that LISP first appeared in 1960 when the specification was published. We unfortunately don't know the year that the interpreter was implemented, although that year might have been 1960.
