overridden in sqlalchemy.dialects.mysql.ENUM, sqlalchemy.dialects.postgresql.ENUM, sqlalchemy.dialects.postgresql.INTERVAL

Given an impl, adapt this type's class to the impl assuming "native". The impl will be an :class:`.Emulated` class but not a :class:`.NativeForEmulated`. e.g.: postgresql.ENUM produces a type given an Enum instance.
