I think we could do ourselves a favor by taking the feedback seriously and
not being so dismissive of criticism. There are pros and cons of the various

Hiding behind DRY for the importing situation is not productive.

The change in trunk fixes the problem for every class that does not
have a __del__ attribute. Classes that have a __del__ attribute may
cause a memory leak (on cpython, not on jython).

I think I've narrowed down the problem - web2py doesn't escape

All I know is that tables are issued as lowercase, but you can still access
