You probably figured this out, but what you want is something like:
(map rand-int (repeat SIZE MAX))

In fact - I didn't think of this - thanks! This is what I used:
(map rand-int (repeat Integer/MAX_VALUE))
I have been around since the beginning of Clojure

There is something to be said for that function. At least it has no
side-effects ;)

(rand-int 49) will produce one integer, and repeat will repeat it 10
times, that is why you see same number repeated.
How embarrassing!
As soon as I switched my machine off last night I realised rand-int
was only being called once - of course it
Why presumably with side effects?Otherwise you would use repeat. A pure
function returns the same value every time, so there is no reason to call
it repeatedly.

Yup, that makes sense.
Random numbers are side-effecting (is that the right term?) and

Hi,
(rand-int 49) will produce one integer, and repeat will repeat it 10
times, that is why you see same number repeated.
To fix this use:
user= (take 10 (repeatedly #(rand-int 49)))
