} ok my $data = pack('u', @data), 'packing data should succeed';
perldoc -f pack:
* Each letter may optionally be followed by a number giv-
ing a repeat count. With all types except "a", "A",
"Z", "b", "B", "h", "H", "@", "x", "X" and "P" the pack
function will gobble up that many values from the LIST.
A "*" for the repeat count means to use however many
items are left, except for "@", "x", "X", where it is
equivalent to 0, and "u", where it is equivalent to 1
(or 45, what is the same). A numeric repeat count may
optionally be enclosed in brackets, as in "pack
'C[80]', @arr".
...
The repeat count for "u" is interpreted as the maximal
number of bytes to encode per line of output, with 0
and 1 replaced by 45.
So it's only packing the first element of the list.
Even if you changed the pack to "uu", since two uuencoded strings
concatenated together are essentially equivalent to concatenating the
original strings, you'll never get back exactly what you started with,
but rather the concatenation of them.
