Actually, I think that something more general would be most welcome.
It should include a mean to read the rule being reduced.  If you take
a look at what Yaxx is doing, that's exactly the same need.  I also
remember that once Greg McGary had similar needs to improve the way
trace (YYDEBUG) were issued for his specific job.

Also, I'm trying to stop using this CPP syntax, and rather use new
Bison directive.  So I would like to propose something more like a
%prereduce, %postreduce.
