Initial casting implementation
Explicit casts can be performed with the syntax 'cast<type>(input)'
and implicit casts can be performed with the syntax 'cast(input)'
where the output type is determined by inference.
To prevent casting shenanigans we only allow casting of primitive
types and of types to themselves (essentially creating a copy).
