There's two ways to get rid of the reflection warning:
1) another function, appropriately type hinted
2) explicit conversion to long
According to my measurements for this particular case, option
I ran into this exact issue on an alioth benchmark.
Adding the explicit (long ...) conversion gets rid of the reflection
warning, but didn't have a significant effect on performance.
The inner loop is still boxing the return value.

Thanks!
Though it is not obvious IMHO.

Looks that way. The following code has no reflection warning:
(loop [x 1 changed 0]
(if (= x 10)
changed
(recur (inc x)
(long (loop [y 1 changed-y changed]
chang

Hi,
Is it a bug or I'm doing something wrong? I can't get rid of
auto-boxing in the second example, neither by type hinting nor by type
coercing of "changed*" locals.
(set! *warn-on-reflection* true)
This compiles fine:
(loop [x 1 changed 0]
(if (= x 10)
changed
(recur (inc x)
