On IRC, Jonathan said that 1 is basically an Int, which is something like a boxed int. So whatever operation works removes the box, and puts the result in the variable. However I wonder how well that's going to work, since Int can store arbitrarily large integers, while int can't. What happens on overflow? Cheers, Moritz
