Where do we draw a line for "language"?  Certainly recursion is evident in
mathematics that far predates programming.  Would you consider Church's
thesis[*] as defining a language?  Some folks figure it as a direct
progenitor of LISP, and recursion certainly figures in heavily.

[*] _The_Calculi_of_Lambda_Conversion_, Alonzo Church.  (I think it's 1940,
Princeton)
