This only works for functions; if you try it with a method, it will fail. It does work for both local package and imports. For now, it tells you when it thinks it sees either a declaration or a call of such a function (this will normally be silent since no existing code uses this pragma). Note: it appears to be really darn hard to figure out if this pragma was set for a method, and the method's call site. Better ir.Node wranglers than I might be able to make headway, but it seemed unnecessary for this experiment.
