If you are coming from another language, be it C or Perl or whatever, it often looks like this: int yada_yada (int whatever) { int temp_var = whatever*2; int temp_var_2 = ... // etc. } My experience, which is totally unscientific (on the other hand I don't know if Stalin ever read Das Kapital) - nevertheless it seems to work great if you just substitute all those local variables with let (and `let*') - you get a really neat, well-defined, all-but functional Elisp world to play with. -- underground experts united
