First, you cannot call an abstract function.

Correct that, either by making the function concrete (elide "abstract" =
and provide a body), or by deriving from the controlling type and =
providing a (concrete) function for the derived type.

Then, to convert between any two compatible types you just write

  Target_Type (Object_Of_Source_Type)
