I'm immediately put off by any system that doesn't let me figure out WTF something actually is until runtime. I should be able to learn most of what I need to know about a codebase with a basic text editor and grep. Some questions should be for documentation to answer, but "what the hell is this variable representing?" isn't one of them. I prefer to let my code and my tools remember stuff for me. Rails and similarly-magical Ruby systems have too high a (human) memory overhead for my taste. Hard to jump in and out of if it's not the main thing you do every day.
