1982 was right in Lisp's heyday and I expect the major implementations
all had macros (Maclisp, Lisp Machine Lisp and its descendants, Nil,
Spicelisp).  Scheme was around and didn't have macros but I don't think
it had fexprs either.

I think that list is pretty bogus.  The main characteristic of Lisp imho
is lambda calculus and lambda binding.  In order to even have a local
variable in a PostScript function, you have to literally push a
dictionary on the evaluation stack and invoke BEGIN, then later END to
pop the dictionary stack, like Forth wordlists.
