@ksaj @praetor That depends on the type of output you're looking for, and it's more of a tooling issue than a language issue. The integrated graphics tools I've added to Kap would be trivial to add to Lisp as well. It certainly was very easy on the Lisp machines.
By the way, I implemented your code in explicit style in Kap, just to show that you can write code that way too.
