Please don't respond to threads that are seven years old. Having said that
the behavior is reasonable and the behavior you and the O.P. expect is not
reasonable. Consider the following examples:
result := strings.Split("abc", "")
result := strings.Split("ab", "b")
result := strings.Split("", "")
The first statement yields a slice of three elements. The second a slice of
two elements with the second being an empty string. What should the second
statement yield? A slice of one element (the empty string) or an empty
slice? The former is consistent with all the other cases while the latter
is inconsistent.
