@ferdymercury While I fear, in the wild, one might find the hand-written loop more often than your (better) way leveraging the STL, I think your version of course deserves to be mentioned too. I just added it to README.md. Thanks. 🙂
:) nice, thanks

Wouldn't it be a more fair comparison to compare in the https://github.com/Dobiasd/FunctionalPlus/blob/master/README.md
auto cutest_cat = fplus::maximum_on(std::mem_fn(&cat::cuteness), cats);
with:
auto cutest_cat = *std::max_element(cats.begin(), cats.end(), [](const cat& c1, const cat& c2) { return c1.cuteness() < c2.cuteness();});
?
(#include is needed)
