Which reminds one - this class should obviously have a method for retrivieng the original key value, given a matching key -
d.canonical('foo') -> 'Foo'
I don't know. Is there any use case? (sure, it is trivially implemented)
Well, I'd expect it to simply be there. I had not thought of other usecases for the transformdict itself -
Well, it is not here for dict, set, etc.
For example, in latim languages it is common to want accented letters to match their unaccented counterparts - pick my own first name "João" - if I'd use a transform to strip the diactriticals, and have an user input "joao" - it would match, as intended - but I would not be able to retrieve the accented version without re-implementing the class behavior.
Interesting example, thanks. Regards Antoine.
