How can I lexically bind names like let does in a macro, when names

Using eval is not really a solution.
(def foo '[a 1 b 2])

will not.
No, for that you need to make the macro

I'm not a big fan of option 1, because you have to

Does anyone else suffer from occassional incorrect indentations in

Thanks Meikel,
your negative answer actually helped me analyze my problem better and
get the distinction run time / expansion time straight. I figured that
the names of the bindings are already there at expansion time and it's
only the values that I need to retrieve at run time.
So this version

Hi, Tim,
I'm not 100% certain what is going on here, but I do know that, in
general, binding and loop/recur should not be mixed.
recur is not true recursion -- it's more like a GOTO. The binding
macro establishes thread-local bindings using the static methods

Yes. But val-fn might also be exactly that: a function
which gets the value by some others means than
a map. I'm not
Is this just me, or does anyone else have this issue?
I haven't had your exact problem, but sometimes it seems to
incorrectly maintain depth at the top level, so I'll end up with
something like

(defn bar [a]
...)
(defn baz [...]

Which vim are you using?

I cleared down my Vim settings back to the defaults, and indentation
As I said, the example was stripped down for simplicity, and that
simple version doesn't make much sense other than for communicating my
problem.
My real val-fn is not a map, it's indeed a couple of functions,
applied to some data that's passed in. But the result of that acts

I think so. Untested:

([key val db]
(swap! db assoc key (cons val (db key))
