Detailed Description

Range types are limited to a complete range that can fit in 32-bits.

(e.g., 0..(2^32)-1 or -(2^31) .. (02^31)-1. This cannot represent ranges like TIME (defined in the standard library). The TIME range requires 64 bits (e.g., the range of time is 0..2^60). A special type is provided for this range (we'll see if this special type was a bad idea or not).
