-/**
- * Q: What is this gross function?
- * A: Currently, this API is inconsistent with the rest of the library, whose
- * principle is that the "element being operated on" (in this case, the target
- * string) should be the first element. This temporary function will be used
- * to correct that inconsistency.
- *
- * Q: Why are you disrupting my workflow?
- * A: We recognize that this will be disruptive in the short term and apologize
- * for the inconvenience. However, it provides the benefit of predictablity
- * for all future users of the HSL.
- *
- * Q: But why now?
- * We are expecting to mark the HSL as 1.0 soon, so this is our only chance to
- * fix this.
- *
- * Q: Okay, fine... what's the game plan?
- * A: All uses of Str\split will be codemodded to Str\split_args_switched, and
- * Str\split will be temporarily deprecated. After a short period, Str\split
- * will be fixed, all callsites will be codemodded back, and this function will
- * be removed.
