I would say that he has an enormous amount of experience with several languages. He lists on his webpage: "Programming languages used over the past 39-years include C/C++, Common Lisp/CLOS/MOP (and other Lisp varients), ALGOL, FORTRAN, PL/1, SNOBOL, numerous assembly languages, and others."

So, he probably could have written it in C++ (or SNOBOL ;-) ), but he chose to do it in Lisp.




No, he could not have (short of bootstraping a Lisp system from C++). I, for one, have much more C++ experience than Ocaml experience. I am far more efficient with Ocaml: typically, my Ocaml programs are 3 to 5 times shorter, takes half the time to program, and almost no time to debug.


I have 10 years of C++ experience, and 1 year of part-time Python experience. I needed to create a simple graph algorithm to find maximum Hamiltonian paths. It took me 1hr to get it running in Python and 6 hours to translate it to C++.

It is amazing how much Python (and other high level languages such as lisp, Ocaml) allow you to focus on the problem you are solving not the irrelevant details of the solution.
