That's just plain broken.

The "#!" line has to be first thing in the file for it to be
recognized.

Apart from that, my personal opinion is that comment blocks like that
are bad practice.  They're too often wrong (e.g. file got copied
modified, but comment block not updated), and the right place for
metadata like that is the filesystem and the source-control system
(git, mercurial, subversion, CVS, whatever -- anything but VSS).
