The (def g) in your example has the same effect as the (declare foo) in my example.
I discussed two problems. The first problem, which you addressed, was mostly just a warm-up for discussing a related problem that is more severe. Where can I put (def g) so that two files can "require" each other? This is not a rare problem for me. Like Mike Anderson, I work around it by putting extra thought into which package-level dependencies I will allow, which sometimes necessitates creating more or fewer packages than I otherwise would have created.
