So they optimized from Vec to Box, but they're still using Box all over and spending 16 bytes on it? The things they're boxing need 2 bytes for length, and their memory use is low enough that they could cram the pointers into 4 bytes. Trying to pack that into 6 bytes is probably too much fuss for the benefit, but I see no reason to use more than 8 bytes.
