Subject: 29.4; cperl-mode __END__ is incorrectly handled
Date: Sat, 8 Mar 2025 10:34:20 -0500

Hi

Given the following cperl-mode program, test.pl

    # -*- mode: cperl; -*-
    print "hello\n";
    __END__
    This is not
      perl code!

The lines after the __END__ are treated as perl code. They are syntactically colored and indented
which is incorrect. In perl, __END__ defines the end of the Perl code in the file. Any text that
appears after __END__ is ignored by the Perl compiler.

All lines after __END__ should be treated as comments.

Thanks
John
