regex - Split a string on whitespace in Go?

Question

Given an input string such as " word1 word2 word3 word4 ", what would be the best approach to split this as an array of strings in Go? Note that there can be any number of spaces or unicode-spacing characters between each word.

In Java I would just use someString.trim().split("\s+").

(Note: possible duplicate Split string using regular expression in Go doesn't give any good quality answer. Please provide an actual example, not just a link to the regexp or strings packages reference.)
