declarative_base() inheritance breaks super() [0.6.4]

[Former user]

super no longer works if you inherit from a declarative class and that declarative class is first in the inheritance list.

I've attached an example script that demonstrates the init of a Mixin class being ignored. It also includes a work around by carefully arranging the inheritance order. Finally, it has the same inheritance demonstrated with standard python objects to show expected behavior.

that's the documented default behavior of declarative_base() ^1 2 3^. To not apply a default __init__:

Base = declarative_base(constructor=None)
