Thanks, Tom!  I've read the doc several times and somehow never noticed 
that it can even be read in the way you say, but you're right, that 
fixes it. (well [% FOREACH sccs = s_to_c.keys.sort %] does :)
I'm curious why it behaves that way instead of the always valid and (to 
me anyway) much more obvious semantics of key order?  Especially given 
that you can always do hash.values.sort if the values are sensible to 
sort on, unlike the hash-ref addresses - I guess - in my case.
Thanks again, Dave
