Hello Thomas,
I reply below, but unfortunately, only with more questions.
Best regards

Could you please elaborate? If your method is virtual, why can it not be
template? In what way is it different from the virtual template member
functions which are used in the template class glucat::clifford_algebra in
GluCat, for example? See
These functions are inherited at compile time by the template classes
glucat::matrix_multi and glucat::framed_multi, using a variant of the
Barton-Nackman trick, otherwise known as Curiously Recurring Templates.

This part of the Wiki talks about runtime polymorphism. The template class
glucat::clifford_algebra uses compile time polymorphism. Do you need runtime
polymorphism or could you do what you want using only compile time

I don't know. I am also curious to find out.
