I think there are two solutions. The first is to use a direct Table
contruct within the class definition:
class MyClass(Base):
__table__ = Table('my_class_table', Base.metadata, ...
The second is to apply a unique index after the fact:
my_index = Index('myindex', MyClass.col1, MyClass.col2, unique=True)
I like the first solution, so I'm not going to test the second today.
