binary parsing

My very humble first attempt at obfuscation.... Hope this can be an initiator for me into deeper unbeaten paths...
print join(' ',map{unpack("A", pack("B8",$_)),''} qw( 01010000 01100101 01110010 01101100 00001010 01001101 01101111 01101110 01101011 01110011 00001010 01010010 01101111 01100011 01101011 01110011 00001010 ));

    This is surprising
    $ perl -le'print length unpack "A", "\n";' 0

    But documented.

      It seems that the output is different on an Win32 XP system...
      perl -le"print length unpack "A", "\n";" 1
      Could you please direct me in which side of the documentation neighborhood that this is reported ?

        Your quoting is broken. You are doing

        >perl -le"print length unpack 'A', \'n';" 1

        which is the same as

        >perl -le"print length unpack 'A', 'S';" 1

        If you fix the quoting, you get the correct result.

        >perl -le"print length unpack 'A', qq{\n};" 0

        pack says "When unpacking, «A» strips trailing whitespace and nulls".

    I like this for its aesthetic beauty. You could have written everything on one line, but you have a nicely formatted pattern to mesmerize and contemplate.
