Re: [Numpy-discussion] Proposal - extend histograms api to allow uneven bins

Just a few thoughts re: the changes proposed in https://github.com/numpy/numpy/pull/14278 1. Though the PR is limited to the 'auto' kwarg, the issue of potential memory problems for the automated binning methods is a more general one (e.g. #15332 ). 2.
