If you write Go code, you will realize you will actually not hit that problem often at all.
Right now the annoyance I hit more often is the inability to map a []Foo on an attribute .Name (string) to get a []string. I do that in ruby all the time, and with Golang it really sucks to do a for loop to collect stuff appending to a new array.
people.map(&:name) => ["Joe", "John"]
vs
a := make([]string, 0)
for _, p := range people {
a = append(a, p.Name)
}
