First, as others have said, the downloaded example is a far cry from an OS, simply because it could not hope to operate without an underlying OS. When you use the 'print' function in Perl, the instruction eventually gets handed down to the OS to discover what the STDOUT is.
It seems obvious that the authors of the 'OS' project, through well-intentioned, are needing of an education on OS' in general.
It seems to me that Perl is much more a language designed to extend the capabilities of a given operating system rather than circumventing it entirely. Current research in OS' is going on at MIT.
