Several SRFIs, R6RS, and most Scheme implementations support some sort of uniform packed integer vectors. In particular, these are necessary for efficient binary I/O, and for memory mapping, so WG2 will certainly want them.
Do we provide a syntax and basic API for these in WG1?
The WG voted to adopt BlobsCowan.
WG1 voted to accept BlobsCowan (the WG1 portion only)
See BlobsAndSRFI4SnellPym for some thoughts on this (regardless of which WG1 supports what bits)
