Arbitrary precision integers are quite a performance burden and they are
rarely used. I would not expect a language that is trying to be efficient to
impose arbitrary precision integers (or floats).
In Haskell, Int gives you the standard signed, fixed size integer for
your machine, and Integer gives arbitrary precision integers. Int8,
Int16, ... provide signed ints of a known size, and Word8, Word16 give
the unsigned.
They are all instances of Num, so integer literals will be whatever type
is needed.
