But....but... in each of these cases where there are two strings, the strings also submit their size after the data, thus these would not be equivalent:

{ "foo", 3, "bar", 3 } { "foob", 4, "ar", 2 } { "fooba", 5, "r", 1 }

Or am I missing something?

Thanks

Yes, currently it works fine(as you described). Peter was using that as an example why we add size of range when hashing. To avoid collisions like this. I was basically asking why hash_append of span<char> also hashes span size since I expected it just consume the bytes span points to.
