I don't see a lot of advantages in inflicting
behavior onto objects through a containment hierarchy. But then, I didn't read
the original paper so please prove me wrong.

I think that TTW scripting and heavy duty application development are very
incompatible with each other, so that's not a problem :-)

One of the reasons I am seriously considering to migrate our production
database from PostgreSQL to ZODB. I am about to implement our product
database, and
and len(self.dbnode.objectMap()) > 0
except:
return 0
def main():
from zidle import App
DbBrowser(App)
if __name__ == "__main__":
main()

Hit "dbbrowser.DbBrowser(App)" in the IDLE console and have fun.

but I'm talking without too much thinking here, I think
support for assertions in Python should be based on generic support
for metaprogramming - there's more than DBC that could benefit from
that (aspect-oriented programming, etcetera).

The usual answer of an OO guru here is that if statements are considered
harmful, and that if statements that check object types are considered very
harmful. The modern variant is "these are strong refactoring smells".
