How to sort slice of 32bit integers, I know about “sort” packege’s Ints method but unfortunately it accepts only slice of ints
By wrapping in a very simple type and then implementing sort.Interface for that.

Simpler solution with sort.Slice: https://play.golang.org/p/9s_noUV5sDA

Nice, I have to remember that one! Would have saved me a lot of lines in a couple of projects…
It’s actually fairly new! Since 1.8 https://golang.org/doc/go1.8#sort_slice

When you coerce your slice into the type byValue and the call to the sort function looks really nice:
sort.Sort(byValue(f))
