A while ago I was attempting to swig a c++ library that did exactly this, but
ran into problems when I couldn't overload the individual comparison operators
for a python class, e.g. consider (assuming Table.__getitem__() returns a Column
object):

    t = Table('foo')
    s = Select( t['col1'], t['col2'] )
    s.where( t['col3'] > 5 )  # oops, not possible

back when I was doing this, people were saying comparison operator overloads
would be implemented in 1.6, but I don't know if that has happened...
