hi all, can i overwrite the behaviour of <= operator for a squeak class?
Yes, of course. Look into the instance protocol of Number to see an example. You can add the following method to any class:
<= anObject self halt.
When you add this to the instance protocol of Set, you can evaluate
Set new <= 5
and you will the the halt in the debugger.
It seems I fail in doing it...
