Edit. Actually, different groups aren't necessary:

>perl -wE "say for unpack '(CX/xX.@0x/A)*', qq(\03ab\05cdef\06ghijk)"
ab
cdef
ghijk

>perl -wE "say for unpack '(CCXX/xXX.@0xx/A)*', qq(\x03\x04Hi\x43\x08H
+ello!)"

Either 1st or last group is built differently, so as not to hit "X(x) outside of string in unpack".
