Comment (by simonpj):

 > But with your fix for matching strict constructors, is there any reason
 to prohibit it aside from the as-yet-undecided static data optimization?

 I don't know and I don't even want to think about it until we have a
 powerful reason for wanting it.  It feel Wrong Wrong Wrong for a passive
 data constructor to start rewriting itself.
