Array module
This module contains functions for manipulating and inspecting arrays. All of the functions will work on arrays of any type.
It is automatically imported (via the Prelude module) unless
the -noprelude compiler option is used. Almost all programs
and modules will need to import this module.
Exceptions
- OutOfBounds - Attempt to access an out-of-bounds element.
- ZeroStep - The step in a range may not be zero
