Ok, this is in cvs now. Examples:

==> put_uint32 B (-2) (uint32_vect [90..94])
()

==> uint32_list B
[92,93,94,103,104,105,106,107,108,109,110]

==> uint32_list $ get_uint32 B (-2,3)
[92,93,94,103]

==> uint32_list $ get_uint32 B (8,100)
[108,109,110]

Note that these operations are all safe in that indices are
automatically confined to stay within the bounds of the target vector.

Here's how you can manipulate a string represented as a byte string in a
given character encoding:

==> def S = bytestr ("Hello world!","latin1")

==> put_uint8 S 3 $ bytestr ("äöü","latin1"); bstr S
()
"Heläöüworld!"
