Perl 5.36.0 synopsis example doesn't work for feature 'class'

I'm taking an example from Perl's documentation:

https://perldoc.perl.org/blead/perlclass

and trying to execute the following script:

use v5.36;
use feature 'class';

class My::Example 1.234 {
    field $x;

    ADJUST {
        $x = "Hello, world";
    }

    method print_message {
        say $x;
    }
}

My::Example->new->print_message;

but I get this error:

Feature "class" is not supported by Perl 5.36.0 at /home/con/Scripts/class.pl line 4.
BEGIN failed--compilation aborted at /home/con/Scripts/class.pl line 4.
Command exited with non-zero status 255

I'm copying the script exactly from the manual, yet the script doesn't work.

Is this a bug, or am I doing something wrong?

Solution

  • From your link:

    You are viewing the version of this documentation from Perl blead. This is a development version of Perl.

    If your code does not run, then you are likely using a different version of Perl. Perhaps you have the standard version of 5.36.1, which is currently the version documented by this link:
