[Python-Dev] PEP 455: TransformDict (original) (raw)

It strikes me that there could be an alternative approach to some of the use cases discussed here. Instead of a new type of dictionary, the case-insensitivity problem could be solved with something akin to a * CaseInsensitiveString* class used for keys within a standard dictionary. This would be very similar to a normal string except with comparison and hashing. It would mean that CaseInsensitiveString("Foo") is considered equal to CaseInsensitiveString("foo") and allow code such as the following:

headers = {} headers[CaseInsensitiveString("content-type")] = "text/plain" headers[CaseInsensitiveString("Content-Type")] "text/plain"

This would obviously also be usable in other places where case-insensitive strings are required.

Just my two pence/cents/other minor currency units. Nigel
