P(ythonic)L/SQL?

I'm itching to begin creating a bunch of PL/SQL packages that will emulate certain handy Python features. Before I sink too much time into it, does the LazyWeb have anything to recommend? Or, perhaps, volunteers to help make the dream come true?

I want to start with a package for Pythonic string manipulation:

'The {0} brown fox jumped over the {1} dog'.format('quick','lazy')
.join()
.split()
.splitlines()
... and so forth

I think this package would not just implement the ones that don't exist in SQL or PL/SQL, it will provide Pythonically familiar names and interfaces to the ones that do exist.

Granted, there's only so Pythonic you can get in PL/SQL. A perfect set of packages would be a heroic task. Still, it's easy to imagine helping PL/SQL to suck less...
