If you asked this 20 years ago I would have no reservations recommending Scheme. It has always been a good language for creating domain-specific languages. ...

I notice in stack based languages certain symmetric programs reduce to no-ops: f1 = [swap swap] = [] f2 = [dup pop] = [] f3 = [cons uncons] = [] f4 = [dup swap...

In Joy the expression: [1 2 3] Should have a type of "list of programs" but instead it has the type "list of ints". I find this confusing. Do we just say in...

Hi John, Consider the following: sum = [+] fold; [[1 2] sum] => [3] [[1 dup] sum] => ??? There is a fundamental difference between the value 1 and the program...

Hi John, I appreciate you discussing this with me. So the following is fine: define f = [1 1] + fold However the following is no good: define g = 1 define f =...
