The unwanted() routine needed to add an explicit sink to certain methods found in a block-final Want node. (Method calls for dispatch:<.=> and Pair.new are exempt, however. In the case of .=, it is 'nosink' because it's essentially going to cause a side effect anyway, and doing it twice tends to drain Seq prematurely if that's what .= returns. With Pair.new, wrapping in .sink suppressed sink warnings on useless use of pairs.) Other than those exceptions, it seems more reasonable to default method calls to sinking on the chance that the method will return a sequence that needs to be iterated for its side effects.
