ok, I see and take your point.

The 'behavior' parameter should be optional and used only if you have
two or more behaviors introducing the same field name. An exception
should be raised if you are trying to set a value in such a conflict
case without explicit naming of the behavior. Likely most behaviors
would use distinct field names...so a conflict would be a rare case.
