Hey @felipesere! -- thanks so much for this PR! I noticed #384 partially overlaps with this PR. I would've left some notes on this PR, but basically #384 was exactly what I was hoping for these methods, so I've gone ahead and merged that instead. I still want to take a moment to thank you for the work you've done here! -- I've seen you've put in a few patches, and they're all really good! I'm going to go ahead and close this PR in favor of #384, but please don't take it as a discouragement from continuing to contribute. I'm really stoked you've been helping out, and would love to continue to have you here! Thanks so much! |

Theoretically its was possibly to create an equivalent of max_by by using min_by.
That would have been awkward to read for users though.
I first tried to Box the comparison function and simply passing it down from max_by to min_by with
reverse()applied. That got too tedious and meant users were exposed to the Box.This variation adds a new field to the strut - now renamed MinMaxBy - that tells us whether we are maximising or minimising.
