      Less one stroke ...

      perl -e 'print chr for qw(78 111 119 32 72 105 114 105 110 103)'

        How unsurprising that we all came up with the same solution:

        perl -e'print chr for qw( 78 111 119 32 72 105 114 105 110 103 );

        was what I did before I even saw the replies.

        Hooray for laziness.

          Here's some packing:

          perl -e'print pack"C*",78,111,119,32,72,105,114,105,110,103'

          and if we can require the user to hit Return + Ctrl-D:

          perl -pe'$_=pack"C*",78,111,119,32,72,105,114,105,110,103'

      What's sad is that I don't even understand why that works. Nice job, though. :)

        From 'man perldata':

        A literal of the form "v1.20.300.4000" is parsed as a string composed
        of characters with the specified ordinals.  This form, known as
        v-strings, provides an alternative, more readable way to construct
        strings, rather than use the somewhat less readable interpolation form
        "\x{1}\x{14}\x{12c}\x{fa0}".  This is useful for representing Unicode
        strings, and for comparing version "numbers" using the string compari-
        son operators, "cmp", "gt", "lt" etc.  If there are two or more dot

  Why write code? I just read it, that was faster than typing a program and the data.
