Comment (by simonpj):

 The return/pure thing presumably arises because we have `return = pure`,
 or vice versa, and one is "shorted out" in favour of the other.  See
 `SimplCore.shortOutIndirections`.   Would someone like to see if this is
 true?

 If someone cares to confirm this, then perhaps `shortOutIndirections`
 could choose whether to elminate `return` or eliminate `pure` based on a
 lexicographic comparison of their names?

 Would someone like to see if this would work?

 Simon
