oh wait...I take a look on binding and with-binding* realesation.

Why with-binding* function wasn't write like this:
(defn with-bindings*
[bindings f args]
(assert-args binding

Hi!
I was playing a bit with with-bindings* function, but I got error
every time.
I've tried:
(def a 5)
(with-bindings* {a 3} println a) ;; got java.lang.Integer cannot be

Yeah.. That function is very confused. I didn't check it, sorry.
I don't understand the reason to make the argument binding-map:
for example, using binding macro:
(binding [a 5] ...do something...) ;;using vector to contain bindings.
but using with-bindings*:
(with-bindings* {#'a 5} f args)

Beware the Leopard!
user= (def a 5)

with-bindings* expects the keys of the bindings map to be Vars, not symbols.

ok...Then what was the reason to use map instead of vector as usually?
