NAME

Math::Polynomial::Generic - history of a discontinued module

REMOVAL NOTICE

Math::Polynomial::Generic was an extension of Math::Polynomial that did not make it into a permanent release.

It had been declared experimental and its interface as not to be taken for granted. The intention was to give users more expressive flexibility through a kind of polynomial object that was not bound to a particular coefficient space.

This experiment turned out as a failure. Coefficient spaces need to be specified at one point, and delaying this part of proper initialization did more harm than good in terms of clarity.

Therefore, Math::Polynomial::Generic was removed from the Math-Polynomial distribution after a two-stage deprecation period.

Technically, before its actual removal it was replaced by an empty module in order to neutralize incompatible code in older versions.

MIGRATION

Old code still using this module can easily be fixed.

Instead of the symbol X, a variable $X that is initialized as Math::Polynomial->new($zero, $one) with appropriate coefficient values $zero and $one can be used.

C($coeff) can be replaced by Math::Polynomial->new($coeff) or it can be defined locally as a small wrapper for the same.
