Research direction
Start with the issue's references to DLMF §15.2 and Mathematica's Hypergeometric2F1Regularized to understand the requested mathematical behavior. Trace the existing _₂F₁ implementation and its handling of negative-integer c values. Done means the regularized variant is computed and the ordinary function is defined through gamma(c) times that variant, with behavior checked around those c values.
Written by the indexing model from the issue text.
Description
_2F1 sucks compared to regularised _2F1 (bold F in https://dlmf.nist.gov/15.2 or Hypergeometric2F1Regularized in mathematica), as the regularised variant avoids the artificial polls at negative integers for c. We really should compute the regularised version and then define
_₂F₁(a, b, c, z) = gamma(c)*regularized_₂F₁(a, b, c, z)
