READ isn't a reserved word in Perl, but
read
is. But it's fine to use filehandles with the same name as
(some) all-caps words with a special meaning, as shown below:
#!/usr/bin/perl
use strict;
use warnings;
open BEGIN, "/etc/passwd" or die;
print while <BEGIN>;
__END__
The program compiles and runs without problems.
