discussed previously in

I tried doing this myself, but don't know enough of the internals to get this done on my own.

it looks like these need to be modified

* sqlalchemy/sql/default_comparator.py
* sqlalchemy/sql/operators.py

but not sure about

* sqlalchemy/sql/compiler.py

there are probably more files.

if someone can get one working, I can do the rest and build out tests.
