If the terminating identifier is on the last line
of the program, you must be sure there is a new
line after it; otherwise, Perl will give the warn
ing Can't find string terminator "END" anywhere
before EOF....
I'm not familiar (haven't read Programming Perl, yet) with this form of the
here-document ("self-terminating"?), but I think it's the same problem
mentioned in the citation.
