Hello fellows
The following code (playground <https://play.golang.org/p/b9rMAK91Ns>) :
//
// I am in Philadelphia, and I want to visit other cities
//
itinerary := []string{"Philadelphia", "Chicago", "Boston", "Austin"}
//
// I am in Philadelphia, and I want to visit other cities in
alphabetical order
//
sort.Slice(itinerary[1:], func(i, j int) bool {
return itinerary[i] < itinerary[j]
})
is broken for retrospectively obvious reasons. Yet, I scratched my head
for several minutes before finding the bug in my actual code.
So I wonder if this would be a good case for a new vet rule. Something
like "slicing the first argument is not a good idea, it will lead to
something that is either broken or convoluted".
What do you think?
