>>And this can be "totally incomprehensible to anybody but the author". It always is. Code isn't magic, so you have to write whatever logic you would write in one language in another, for any application you would write. The only exception if your language provides abstractions on which you can build on. For example in Perl, you can do a lot of file operations and regex work without libraries. In Java you might need a library, sometimes a combination of libraries, whose documentation one might have to read. Same goes with lisp too. The only difference being, every once in a while one might discover a way to do large patterns of code through simple ways using macros.
