Hi. I have a java class that has 2 methods with same but different arities
(one take no arguments, other takes 1 argument). I create a proxy that
overrides both this methods. The problem is that if no-arg method is called
from this java class - base implementation is called instead of proxie's.

I am very new to Clojure and functional programming in general. I am game

As I tested, looks like when either of the args are double ie. 1.0 instead
of 1
then the code that checks for and shows divide by zero is not reached,
which is this code:
static public Number divide(Object x, Object y){
Ops yops = ops(y);
if(yops.isZero((Number)y))
throw new
Upon further research looks like:
= *(/ 1 0.0)*
Infinity
triggers this method: clojure.lang.Numbers.*divide(long, double)*
*static public double divide(long x, double y){
return x / y;
}*
=* (/ 1.0 0)*
Infinity
triggers this method: clojure.lang.Numbers.*divide(double, long)*
*static public
I've resorted to explicitly calling compile from the REPLin CCW projects.
It's not the best system, but it works.

It doesn't in 1.3 and later, unless you change the definition of twice to

With that change, it works in Clojure 1.3 and later.
