Happy New Year to you, Alex. I reproduced the problem as follows:
user=> (loop [x (byte 0) count 0] (if (< count 10) (recur 0 (inc count)))) java.lang.RuntimeException: java.lang.IllegalArgumentException: recur arg for primitive local: x must be matching primitive (NO_SOURCE_FILE: 57) user=> If the compiler detects that a loop binding evaluates to a primitive, it insists that the corresponding recur argument be a reducible to a primitive as well. You can short-circuit that logic with a type hint, like this: user=> (loop [x #^Object (byte 0)] (if (< x 10) (recur (inc x)))) nil user=> It's ugly but it works. If you change line 65 in your example from "char (.read ireader)]" to "char #^Object (.read ireader)]", the compile error should go away. The example in my previous posting didn't have that problem because 0 by itself is an Integer object, not an int primitive.
