12679	In admin, inlines should be allowed to be properties	mariarchi	nobody	"Currently, if admin class defines an attribute 'inlines' which is not an instance of tuple or a list, django will raise an error.
I believe that this is wrong and contradicts the duck typing philosophy - we shouldn't care that the attribute 'inlines' is an instance of list/tuple, but rather we should care that it is iterable.

The reason why I believe that behavior is wrong is the following:
one might want to define 'inlines' as a property. This might happen when admin class A inherits from admin class B, and class B adds some inlines (that can be useful when developing a pluggable application). If class A has some inlines of its own, it can be useful to declare inlines as a property and then call 'super' to retrieve the inlines of class B."
