The following code is taken from https://blog.golang.org/go-maps-in-action.
type Person struct { Name string Likes []string } var
people []*Person *likes := make(map[string][]*Person)* for _, p := range
people { for _, l := range p.Likes { *likes[l] =
append(likes[l], p) //This line* } }
Am I being paranoid in thinking the line with two likes[l] is actually doing
two lookups ( two hashes, two probes ) and should be eliminated somehow?
Coming from a C++ background ( gophers have mercy :P ), things like this really
bothers me.
