I'm still struggling with how to write the most readable, simple clojure
code
to deal with dynamically bindings.
What is the graceful clojure equivalent of common lisp special variables
for the following scenario.
If I were writing common lisp I'd just do something like (pardon if my lisp
is rusty here):
(defvar *x* 1)
... do stuff with *x* ...
(setq *x* 2)
... do stuff with *x* ...
(let ((*x* 3)) (do stuff with *x*...)
;; do stuff with *x* that's currently at 2
The way I'm tempted to do this in clojure is
(def ^{:dynamic true} *x* (atom 1))
... do stuff with @*x* ...
(reset! *x* 2)
... do stuff with @*x* ...
(binding [*x* (atom 3)] (do stuff with @*x*))
Is that the simplest way to map between the two language scenarios?
Or is there something simpler, perhaps using some var-* apis or what have
you?
