The magical leverage of languages
If I write a straightforward solution to a problem in Clojure, it might take me a thousand lines of code to solve it. To handle all the corner cases and everything, I got a thousand lines of code. However, if I take this other approach where it’s much more indirect, or instead of solving the problem that I have in front of me, I write a language–a DSL. The DSL could take me 500 lines of code to write. That’s a fairly large DSL. Usually they’re much smaller, but it takes me 500 lines of code. Actually, writing the solution in it only takes 10 lines of code.
