CAST explodes with recursion limit

[squeaky]

You are probably meant to always pass one of the classes from sqlalchemy as type parameter. Anyway if you do what I did it it shouldn't explode with recursion limit I guess.

>>> import sqlalchemy
>>> sqlalchemy.__version__
'0.9.7'
>>> sqlalchemy.cast(1, 'text')

• Fixed bug where a fair number of SQL elements within the sql package would fail to __repr__() successfully, due to a missing description attribute that would then invoke a recursion overflow when an internal AttributeError would then re-invoke __repr__(). fixes #3195
