I mean - given no function to retrieve the canonical key,
one would have to resort to:

my_key = data.__transform__(given_key)
for key, value in data.items():

          ....

Which is exactly why I, and others, would like to have the transform function 
easily available.  Besides being able to
use it to get a canonical key, one could use it to get the function itself.  
Yay, introspection!

Well, no, you misunderstand :) The transform function takes an
original key (perhaps "canonical") and returns the transformed key, it
can't do the reverse which is what getitem() does.  i.e.:

Argh, of course you are right.

Still, I think it would be useful to expose the transform function.  Any good 
reason not to?
