| 69 | | All types imported from modules that have not been vectorised are regarded to be scalar types, and they can be used in encapsulated scalar code. If custom instances for the `PData` and `PRepr` classes are provided, these types can also be used in vectorisation code. The latter types have no specialised vectorised representation (as they are scalar) and are abstract; i.e., their constructors cannot be used in vectorised code. An example is the treatment of `Int`. `Int`s can be used in vectorised code and remain unchanged by vectorisation. However, the representation of `Int` by the `I#` data constructor wrapping an `Int#` is not exposed in vectorised code. Instead, computations involving the representation need to be confined to scalar code. |
