ENH: enable mul, div on Index by dispatching to Series by jbrockmendel · Pull Request #34160 · pandas-dev/pandas (original) (raw)

One of the last remaining inconsistencies between Index and Series arithmetic is that division and multiplication is entirely disabled for object-dtype Index, while for Series we operate pointwise. This PR makes Index behave the same way, and simplifies the code by using existing Series-op-wrapping code to do so.
