My personal experience tinkering with Lisp is that it can sometimes be very hard to actually achieve the legendary high performance of SBCL, without your code getting verbose and ugly. Yes, you could ostensibly wrap that ugliness up in macros, but then you're inventing your own DSL and a compiler in the macro engine, which I guess is what the true Lisp nerds live for, but I have too few brain cells and too little time/energy to shave such big yaks.
