Subject: procedures and data
...
When procedure symbols are encountered in the eval stream, they are called
with the next list in the eval stream as the parameter list. A special
prefix character is necessary to explicitly access the procedure-object,
to, for example, assign it to another variable.
A program might look like
+ (2 2)
print ( / (2 f))
Without commenting on the questions raised, I'd just like to point out that the
proposed syntax is "eval-quote" Lisp (as opposed to "eval" Lisp) extended to
non-top-level forms. An "eval-quote" Lisp, such as Lisp 1.5, is one in which
the top-level loop is defined in Lisp as
(defun top-level-loop ()
loop-top
(print (apply (read) (read)))
(go loop-top))
(NB: This is typical Lisp 1.5 programming style--"let" and friends didn't yet
exist.)
