Yes and that is indeed what I did.

However it seems to be bad behaviour by the parser, and locks the spline into a
single-use object.

IIRC, I can use pre-declared splines in sphere_sweep without a problem.

The inability falls under the "contrary to user expectation", and that's why
it's in this section.

Thank you, of course, for providing the workaround.
I wonder how many other things we have like this lurking around in the source.
