in order to be able to warn on redefinition of relationships we need to add
a '+foo' form for relationships. Possibly an env var to squelch the warning

+The warning is spurious as indicated in the RT ticket. Caelum said he will
+fix it and never did anything.

+This conceptually is not a DBIC problem
