// Interestingly, the regular maxItem is twice as fast as this much more elegant version.
// However, you can learn a lot by trying to solve and reimplement common methods with e.g. inject.


f = {|a| a.inject(a.first, {|last, current|
        max(current, last)
})}


// an example array
a = {100.0.rand2}!1000

// evaluating the inject method
f.(a)


// benchmark
{100.do{f.(a)}}.bench
{100.do{a.maxItem}}.bench
