- [bug] TypeDecorator now includes a generic repr()

    that works in terms of the "impl" type by default.
    This is a behavioral change for those TypeDecorator
    classes that specify a custom __init__ method; those
    types will need to re-define __repr__() if they need
    __repr__() to provide a faithful constructor representation.
