add two numbers in the 1-10 range, and you invariably end up with a number 
in the 2-20 range

that is both more (in the low end) and less (in the high end) restrictive 
than the inputs

i don't find that surprising at all; indeed, i wouldn't consider using a 
checked integral class that did not reflect that

but that may just be me, since i can't afford to test at runtime something 
that could have been tested at compile time

other people may have other considerations. which is just fine, a good 
library doesn't try to be everything to everybody
