 Kudos to Allin. This really is great stuff. 
:-) Thanks to Sven for bugging me about this. The enhancement wasn't 
as complex as I feared: a little dose of recursion in the right 
place (though finding just the right place took a while), plus 
application of the parser we use on the right-hand side to the 
left-hand side (in place of the cheap and cheerful ad-hocery we had 
before for the LHS).
