Why do we need this? We typically use the package evalpoly-compile for generating functions implementing Horner's rule.

Ok, but I thought it would make things easy to implement if we do this.

[kgryte]

In principle, we could add a C implementation which is equivalent to the main export; however, it is not something that we'd use in our C implementations. There, we use evalpoly-compile to generate functions AOT and in-line them into C source code. This allows avoiding loop overhead when evaluating polynomials.

That makes sense! Also I understood that it can be tackled in a different way!
