While /F suggested we get off the PIL bandwagon
I suggest we drop the obsession with pointers to memory areas that are supposed to have a specific format; modern data access API:s don't work that way for good reasons, so I don't see why Python should grow a standard based on that kind of model.
Please give us an example of a modern data-access API (i.e. an application that uses one)?
I presume you are not fundamentally opposed to sharing memory given the example you gave.
the "right solution" for things like this is an *API* that lets you do things like:
view = object.acquire_view(region, supported formats) ... access data in view ... view.release()
and, for advanced users
format = object.query_format(constraints)
It sounds like you are concerned about the memory-area-not-current problem. Yeah, it can be a problem (but not an unsolvable one). Objects that share memory through the buffer protcol just have to be careful about resizing themselves or eliminating memory.
Anyway, it's a problem not solved by the buffer protocol. I have no problem with trying to fix that in the buffer protocol, either.
It's all completely separate from what I'm talking about as far as I can tell.
