Ah, the array was a trick I used in java code : because I want to get a
value from another thread, the reference passed to the Runnable must be
final, and the Runnable can't change it, but it can "act on it". So I could
also have created a little class with a field, and the Runnable would have

Hi,
Okay, I'm reasonably sure this is a bug with clojure's eval. Here's an
even more succinct version:
(defn lazy-identity [a]
(if (seq? a)
(map lazy-identity a)
a))
user=> (lazy-identity '(apply + '(1 2 3)))
(apply + (quote (1 2 3)))
user=> (eval (lazy-identity '(apply + '(1 2 3

I can vouch for using SWT with Clojure. There is also no need to
compile you application to distribute it. I posted a little example

hi,
how can i do this in clojure?

def foo(x, y)
x + y
end
def bar

foo(*bar) # this is fine, the result will be 3

bar returns an array of size 2, but foo expects 2 parameters not an

A possible simplification is that Clojure functions implement Runnable

It sounds a little weird to me that you use a synchronous call to the UI
thread (via syncExec and not asyncExec), but then use an asynchronous call
to an agent ?
I don't have repl here to test it, but could you make something simpler,
like creating a mutable structure in the let - an array

I am working with this SWT application. For most calls with SWT, if
you want to request data from a widget, then you must do so through
