Will Span fill the need for FixedArray in Swift?

Approaches for fixed-size arrays

Here are some directions I've been considering, and I'd love to hear the community's ideas and reactions: Tuples as fixed-size arrays This was the approach outlined in our most recent pitch on the subject: we already use homogeneous tuples to represent imported fixed-size array fields from C, and library developers sometimes reach for them manually (usually under duress)…

Will Span be used to represent imported fixed-size array fields from C instead of tuples?
