* This module provides 64-bit signed integers. It should be used in place
* of [int] when this extra bit is required (int's are 63-bit) *and* to make
* sure everything works on 32-bit platforms (where this type will still provide
* 64-bits).
* In short this should be used in place of int's when dealing with values
* that may exceed 31 bits.
* Performance notice: value of type Int.t will occupy more space and
* operations on them will generally be slower than over the int type.
