[IPython-dev] Cell Magic names

I was playing with my shebang magic, and I decided to test something evil:

    @cell_magic('#!')
    def shebang(self, line, cell):
        """Run a cell via a shell command

        The `%%shebang` line is like the #! line, specifying a program
(bash, perl, ruby, etc.)
        """
        p = Popen(line, stdout=PIPE, stderr=PIPE, stdin=PIPE)
        out,err = p.communicate(cell)
        print(out, end='')
        print(err, file=sys.stderr, end='')


Which actually lets me do:

%%#! bash
for i in 1 2 3; do
  echo $i
done

I presume we don't want that to actually work, right?  Kinda fun, though.
