   This is an old feature of some Scheme implementations. There are also books where the Scheme code is written this way, IIRC.

   did you look at the lib? Looks like what many Lisps have. The class stuff is also very Lisp like.

   My impression is that GOAL and Lisp shares quite a bit more. https://opengoal.dev/docs/reference/lib You might want to look at the features of real Lisp or Scheme implementations.

   In many Lisps (+ + +) means this: call the function named + on the two values from the variables named +. The function is then a function object and the values of + can be anything they are currently set to. Thus + serves more than one purp

   yes, that's right. It's additional work. The company I work for has to do it from time to time with Apple's help. We have Mac users who, for example, return locked Macs when leaving the company... we unlock them then with App

    It's a simple quote, but not very useful. The past isn't generally depressing and there are lots of things worth to be remembered. The past is not only in my mind, it is around me all the time and it is the context I'm living

    Lisp code is written in a simpler notation than ASTs, it's written as nested lists of objects. Hierarchical data-structure: the s-expressions are based on nested lists of arbitrary data. Like symbols, numbers, strings and many others.

    I didn't use Interlisp-D systems back in the days. I was as a student only a short time (mid 80s) in a lab which had probably a dozen or more of them, incl. server and laser printer. They were already no longer being used. The lab at t

    That's SLIME specific. SBCL's own REPL has it. * (defun foo (x) (declare (optimize (debug 3))) (let ((n 10)) (break) (* x n))) FOO * (foo 3) ; calling foo (foo 3) We get a break repl:

    Ruby symbols are similar to keyword symbols in Common Lisp. There a keyword symbol is a symbol which evaluates to itself: CL-USER 69 > :a-keyword-symbol :A-KEYWORD-SYMBOL Keywords with a similar name are identical: CL-
