Are you sure this worked in 1.70 but not in 1.71?
if you try
x= Field('uuid',
type=s3uuid,
length=64,
notnull=True,
unique=True,
readable=False,
writable=False,
default="")
print x.type
you get 'string' and not <instance SQLCustomType>.
It is as if something is wrong in the Field constructor but I did not
change that.
