Sure. ;)

The Python->SQL part is perfect for adaptation and, for example, psycopg
has a micro-protocols implementation to help with the adaptation of any
Python object into a valid ISQLQuote one. Why two different systems?
Because transating Python to SQL and SQL to Python are two very
different operations, IMHO.
