Comment (by simonpj):

 Finally there are the multiple occurrences of `ds5`.   I think that `ds5`
 counts as `smallEnoughToInline` and hence `postInLineUnconditionally`
 inlines it in HEAD.  But in this variant I'm not longer sure becuase it's
 outside the recursive loop.  Maybe it didn't start that way?
