Research direction

Start with the Polynomials.PolyCompat entry point and inspect how the deprecated Poly API and missing polyeval name are handled. Update the deprecation and missing-name guidance to point to Polynomial and Polynomial(...)(...), then verify the resulting messages in the relevant compatibility tests, if present.

Written by the indexing model from the issue text.

Description

i really like the new API, whereby one creates a polynomial with Polynomial instead of Poly and then evaluates it as a functor instead of calling polyeval. thanks for that!

however, upgrading is more difficult than it needs to be. one has to read the documentation! gheesh. would be more discoverable were there better deprecation warnings. currently, it just says Poly is deprecated and polyeval is not found. how about saying "use Polynomial instead of Poly" and "use Polynomial(...)(...) instead of polyeval" ?

  Poly{T}

  Type of polynomial to support legacy code. Use of this type is not encouraged.

  This type provides support for poly, polyval, polyder, and polyint to support older code. It
  should not be used for a new code base. Call using Polynomials.PolyCompat to enable this
  module.

help?> polyeval
search:

Couldn't find polyeval
Perhaps you meant polyval, padeval or polyder
  No documentation found.

  Binding polyeval does not exist.
