Yes, dynamic vars do not exist in CLJS, so naturally binding doesn't work
as you would expect.

You cannot do so in cljs though:
http://dev.clojure.org/jira/browse/CLJS-1634
Just in case you expect to write cross-platform code with dynamic bindings.

Yes, that should work fine, do your tests confirm otherwise? Also if you're
not doing a recur there's no reason to use `go-loop` you can just use `go`.

Hi,
can I bind variables, same as I do for threads, for go routines, to be
local only for a particular go routine, and if I can't, how would you mimic
this behavior ?
(defn print-stuff [s]
(println s))
(go-loop []
(binding [*out* (clojure.java.io/writer "foo.txt")]
(print-stuff)))

Usually it's better to create a sentinel (Object.) to lock on to avoid sharing
it. (Well really it's best to avoid locking at all and use Clojure state
constructs if you can.)

The problem here is that you are splicing in obj when there is no need to.
You actually want your generated code to refer to obj. So just
(defmacro mac1 [& body] `(locking obj ~@body))
is fine.
dennis' solution will work too, but it will work almost accidentally? All
blank maps evaluate to the s
I think the reason is in macroexpand-1 result:
user=> (macroexpand-1 '(mac1 1))
(clojure.core/locking # 1)
It's not a valid form to be read and eval by clojure reader,the object form
can't be parsed.
If define obj to be a map {}, it works fine:
user=> (def obj {})
#'user/obj
user=> (mac1 1)
1
u
user=> (def obj (Object.))
#'user/obj
user=> (defmacro mac1 [& body] `(locking ~obj ~@body))
#'user/mac1
user=> (mac1 nil)

you can make that variable "error" as an Agent and change it asynchronously
or as a Ref if you want the change synchronously. other part of the code
remains same.

They are not constants. Locals can be "overwritten" but their data structures
are immutable (by default).

In Clojure you can define a local constant with let, but I need a variable
(I think).
I want to do the following. I have a function that checks several things.
Every time an error is found I want to set the variable errors to:
(concat errors new-error)
Is this possible? Or is there a better w
Phew! Thank you. That did it. I did need to add the nil to each nth
statement, but this helps.

Not sure what you mean by 'row of vectors', and 'break up each row'.

If I have rows of vectors, such as the return from clojure-csv\parse-
csv
["a" 1 "b" 2 "c" 3 "d" 4]
["e" 5 "f" 6 "g" 7 "h" 8]
How can I break up each row?
I've tried doseq in the let statement, but get an error.

One way would be:
(defn map-func
"test map function"

(let [mtr-seq (vector "a" 1 "b" 2 "c" 3 "d" 4)
read-map (apply hash-map mtr-seq)

(let [mtr-seq (vector "a" 1 "b" 2 "c" 3 "d" 4)
read-map ()

I want to load read-map with the keys and values from mtr-seq.
Eventually, this data is going to be from the return from pars
