Comment (by rhaas):

 Replying to [comment:5 sbrandt]:
 > After digging in to this deeper, it seems the real problem is that
 Piraha integration was incomplete. Util_ExpressionEvaluate() is still used
 when expressions are set internally.
 We have actually list of leftover TODO items for Piraha (meeting minutes:
 http://lists.einsteintoolkit.org/pipermail/users/2013-February/002854.html)
 for which we unfortunately never created a ticket so they got lost it
 seems.

 Piranha parameter parser:
 * currently parses only parameter files, plan to extent to all ccl files
 * should use namespace and adhere to Cactus naming and commenting
 conventions: either use C++ namespace cctk (and cctki?) and/or prefix all
 externally visible functions by either cctk or cctki depending on  whether
 they should be user callable or not [NOTE: these are lowercase but they
 should have been uppercase CCTK (RH)]
 * remove and replace existing math evaluator/parser by piranha one to have
 uniform math support
