Explicit recursion works just fine for me and keeps things simple:
pad :: [Word8] -> [Word8]
pad xs = pad' xs 0
pad' (x:xs) l = x : pad' xs (succ l)
pad'  l = [0x80] ++ ps ++ lb
pl = (64-(l+9)) `mod` 64
ps = replicate pl 0x00
lb = i2osp 8 (8*l)
at the cost of (very slightly) hiding data flow.
Seems exactly what you were trying to avoid?
