We seem to be getting mixed up over two seperate issues here, which we
should try to keep seperate:
1. Whether $table style string interpolation is a desirable or
necessary addition to python.
2. How to do variable interpolation in SQL strings.
For my money, issue 2 is addressed as above by Skip (ie let the DB API
sort it out), and the question mark over 1 is: why is $table style
necessary when we've got %(table) style?
