You have your programming language. Now, you design a special-purpose DSL (using macros or whatever) in which to express solutions to your problem. Now you have two languages. (apologies to Jamie Zawinski) The issue is: Management of Complexity, not how to efficiently express complexity. This is why we have layers - layers are a kind of DSL; and this is where most complexity lies. Clear layering -- including defining the functions of each layer -- is how Complexity is tamed. (And this can be successfully done in assembly language, if you want.) The main reason to master weird languages is: Fun.
