The magic of meta-programming (Ruby) vs. magic of macros (Clojure) vs. no magic (Python). This probably comes down to personal preference, and so is a potential benefit of any of them, depending on your preference, but it's a significant difference, so it's worth pointing out. By "magic" I just mean when the system seems to be more doing something much more powerful than you can readily see just by looking at the code. A simple few lines of code are doing all these wondrous things that aren't spelled out completely in the code (unless you peek under the covers and can understand the black arts that lie there). In Ruby/Rails this is the result of a lot of metaprogramming happening, based on conventions (that must be learned). In Clojure this happens through macros that implement powerful DSLs. In Python, it doesn't happen nearly as much. Code tends to be more transparent. This description of ruby, clojure, and python very much matches my experience (though with ruby I'm relying on the accounts of other developers that I know, since I haven't personally used ruby). Why are black arts and opaque code desirable? It's almost a tautology that these things are unmaintainable: you can't maintain code if you can't readily understand it, e.g. if it depends on "black arts", or is not transparent. -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
