I can't speak on the specific merits of this proposal, or whether this kind of functionality is desirable. However, I'm -1 on the addition of a builtin for this functionality (the PEP doesn't actually say that there is another builtin, but the examples suggest so). Instead, putting it into the sys, array, struct, or ctypes modules might be more appropriate, as might be the introduction of another module.
I'd say the answer to where we put it will be dependent on what happens to the idea of adding a NumArray style fixed dimension array type to the standard library. If that gets exposed through the array module as array.dimarray, then it would make sense to expose the associated data layout descriptors as array.datatype.
