I like the idea, but don't think this is a good implementation...

[ghost]

your reply is unclear.
what do you think is bad : use a template filter?
give me direction if you want better...

[ghost]

i give a result example (a wizard session) with a unit test...
I think is a good way to prove what i want to do...

If my first commit is really a bad implementation, this test can validate a better work.

thanks jezdez : in fact, it's more beautiful!

I prefer using the built-in pprint module, which — judging by the test in your patch — does pretty much the same thing.

I have committed a simpler solution in 982f341.
