+      Response: Too much complexity already.

+    - Barry: I'd like to add my own warning action.  Maybe if `action'
+      could be a callable as well as a string.  Then in my IDE, I

+
+      Response: that's the simplest implementation, given that the

+      PyErr_Warn() call, which imports the warnings module.  I see no
