But using the parametric object directly creates a shape, using a spline
doesn't create a shape. (I don't know what I'm talking about, so please
correct me, if I'm wrong.)

Type of spline and values for entries.

A list? Which language?

Do you mean user defined functions?
They are completely programable by the user.
Or do you mean predefined functions?
Spline are declared at parsing time, so they can't be predefined.

But perhaps splines are predefined (because of the predefined algorithm) and
user defined (because they are declared at parsing time) functions. A
function is a data type, so I think, the answer could be:
A spline is a data type and a function.
