I was considering making this work for DBIC by being able to say "delay
relationship setup until I tell you I've got everything loaded".

But then, obviously, you have to tell it. Which is ok in DBIC, because I
can just have load_classes handle that, but I'm not sure if I can get an
equivalent "magic hook" for CDBICompat - I suppose you could use a source
filter to whack a DBIC->undelay call at the end of the file but, erm, ick.

If somebody finds a hook we can use and writes me some tests I've got no
problem with dealing with the DBIx::Class internals part.
