== Description ==

null is a unique library defined value that is employed in place of [[nil]] in certain areas. It's best to pull null into the global environment if needed to any degree. The type returned by [[type]](null) is 'table', so a special library function, [[non]], is used to test whether a variable's value is nil or null. If either of those values, non returns true, and false otherwise.

local sl = dofile(getinstalldir()..'/lib/simplelib.lua')
null = sl.null
print(type(null))
print(sl.non(null))

--> 'table'
--> 'true'
