如何在不删除分隔符的情况下分割Golang字符串？

Question

According to the answer at How to split a string and assign it to variables in Golang? splitting a string results in an array of strings where the separator is not present in any of the strings in the array. Is there a way to split strings such that the separator is on the last line of a given string?

e.x.

s := strings.split("Potato:Salad:Popcorn:Cheese", ":")
for _, element := range s {
    fmt.Printf(element)
}

outputs:

Potato
Salad
Popcorn
Cheese

I wish to output the following instead:

Potato:
Salad:
Popcorn:
Cheese

I know I could theoretically append ":" to the end of each element except for the last, but I'm looking for a more general, elegant solution if possible.

You are looking for SplitAfter.

s := strings.SplitAfter("Potato:Salad:Popcorn:Cheese", ":")
  for _, element := range s {
  fmt.Println(element)
}
// Potato:
// Salad:
// Popcorn:
// Cheese
