If you don't want the overhead introduced by an atom or (maybe, I'm
not sure) by local vars, you can just instanciate a mutable object.
The simplest being just an array of Objects with just one element.
This can be achieved without java interop by using make-array , aset,
aget ...

Hi everyone:
I'm trying to optimize an inner loop and need a variable that mutates
to make this work. It does NOT need to be a thread-safe variable.
What's the best way to create a plain ol' mutating variable in
Clojure? I know I can always use an Atom, but I was wondering if
there's a more
I suspect the answer will be that I should use atoms (despite the fact
that it isn't completely low level) since I see RH uses those in his
memoization example, which is pretty much the epitemy of optimizing
with a mutating local variable. :-)
