+  * When using native delegations, if an array or hash ref member failed a
+    type constraint check, Moose ended up erroring out with "Can't call method
+    "get_message" on unblessed reference" instead of generating a useful error
+    based on the failed type constraint. Reported by t0m. (Dave Rolsky)
