As dynamic as it needs to be. The built-in array type has to know how
much of the array is really there already, and how to build the rest of the
array on demand.

It's auto-conversion. An "int" declaration is a strong guarantee that
the thing is never going to be required to store a random scalar. On
the other hand, and "Int" declaration merely requires that the scalar
stored "does" Int.
