Oooops, the first 4 lines got lost:

======================================================
__metaclass__ = type

class ModeA: pass
class ModeB: pass
class TypeA: pass
class TypeB: pass
class TypeC: pass
class SubtypeA: pass
class SubtypeB: pass

collect_bases = [(Mode, Type, Subtype)
                 for Mode in [ModeA, ModeB]
                 for Type in [TypeA, TypeB, TypeC]
                 for Subtype in [SubtypeA, SubtypeB]]

count = 0
for bases in collect_bases:
    name = "UserClass%d" % count
    globals()[name] = type(name, bases, {})
    count += 1
