OK, well it sounds you may still be able to use let
instead of setq. 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.
