Well, I think that the idea of a bool being different than an int is often useful.
Yes. E.g., applications to directed graphs.
we can use some version of sum() to add up all the true values.
Unclear, but given the existence of sometrue, it seems natural enough to let sum treat a Bool as an integer. Products work naturally, of course.
I would probably maintain the easy conversion of a Bool array to an Int array, for when you really do need to do math with them.
I would rephrase this. Boolean arrays have a naturally different math, which it would be nice to have supported. It would also be nice to easily convert to Int, when that representation captures the math needed.
We'd want a compete set, many of which already exist. A few off the top of my head: sometrue alltrue numtrue
I'd just let sum handle numtrue.
Maybe mirrors for false: somefalse, allfalse, numfalse
I'd just rely on alltrue, sometrue, and (size less sum) for these.
fwiw, Alan
