New issue 3195: CAST explodes with recursion limit
https://bitbucket.org/zzzeek/sqlalchemy/issue/3195/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')
