-1. What is this good for?

I still can see the value. If you think the codec API is good for such
transformation, why not use it? I.e.

enc,dec,_,_ = codecs.lookup("compress-form-foo")
s = dec(s)

Furthermore, this seems like a form of hypergeneralization. If you
have this, why not also add

s = s.decode("capitalize") # instead of s.capitalize()
i = s.decode("int")        # instead of int(s)

> Any objections ?

Yes, I think this should not be added.
