Comment (by knarf):

 The patch looks ok, but duplicates code from the flesh. However, those
 flesh functions are not accessible to thorns, so that's currently the only
 way.

 Roland: What would it take to provide a function within the flesh which is
 similar to CCTK_ParameterSet (which already knows about expressions) but
 which doesn't actually set a parameter but returns what would be set? This
 could then be used in Trigger so that Trigger wouldn't have to know about
 how Cactus parses expressions.
