Do these sound reasonable?
s8vectorlist
u8vectorlist
s16vectorlist
u16vectorlist
s32vectorlist
u32vectorlist
s64vectorlist
u64vectorlist
f32vectorlist
f64vectorlist
c64vectorlist
c128vectorlist
charvectorlist
It gets a little unwieldy, and "buffer" does get more appealing.
s8buffer
u8buffer
...
charbuffer
