In certain ways, the difference between (Common) Lisp and other languages is the difference between Linux and Windows. When you have a fundamental problem in Windows, your only solution is to wait for a fix then reformat/reinstall. Similarly, when there's a problem in, say, a C compiler, all you can do is code around it, open an issue and wait for a fix in the next release.<p>In Common Lisp? Well, the compiler's right there under these floorboards. Have a long-running web application that's affected by this bug, and don't want to restart it? Just run this in the REPL.
