POV-Ray's parser (currently) isn't smart enough to figure out whether
you want a copy of mySpline or a point on it. In the other two examples,
it knows you are using vectors. Try this instead:
#declare MyVar = (mySpline(pos));
The parentheses get POV to treat it as a numeric expression, so it
evaluates the spline instead of trying to copy it.
