Have a look at turbojson [1], the jsonification package that uses peak.rules [2] and which comes with turbogears [3]. It does exactly what you propose. That it uses PEAK-Rules is probably a good reason to avoid it.

Why?

Also, AFAIK, TurboGears have stopped using turbojson and relies on [simple]json instead.

That might be true for turbogears2 but turbogears1 (which is still in active development) still uses turbojson. Turbogears 1 and 2 diverged so much that it would be more appropriate to call them different names and consider them different projects (I personally use and prefer tg1).

Cheers, Daniel
