Comment (by hinder):

 Regarding the $ signs in the proposed solution in the summary.  Why are
 they necessary?  I believe that Cactus used to support "global parameters"
 which would not have a double-colon as they don't have a thorn, but these
 are not used, and I think the new parser doesn't support them anyway.  So
 an assignment of the form x = y should be unambiguous.  The $ signs seem
 unnecessary (and would have to be quoted if you used this feature from a
 python rpar script).
