I used LPC a long time ago on an LP Mud, so Pike has always had a fond spot in the back of my mind, even if I don't use it now.
However, that works for int and bigint, but Number (double precision) can represent numbers that BigInt can not, and BigInt can represent numbers which Number can not. There isn't a graceful way to automatically promote/degrade one to the other in all cases, and a silent conversion will do the wrong thing in many cases.
heh, yeah, that's where i started too. i don't know how or even if LPC did it, but in pike the transition really is seamless. give it a try. as a naive user i can't even tell the difference (you can see it though if you compare typeof(1) vs typeof(20000000000000000000) (i hope that number is big enough))
