This is a modern reinterpretation of the concept, not the tool. No reason an option can't go at the end unless you're determined to copy limits from the past. If so, maybe just use find and save yourself the trouble. Interspersed/intermixed options have been around for quite a while, though not certain they made their way to golang. If not, the program could handle argument processing itself.
