Re^2: Get element count of CONSTANT list (aref))

++ tybalt89, I had thought about and actually tested that as well, but I can't use that. If I used postfix-deref, then that would force the encompassing distribution (or other consumers) to require 5.20 at minimum, which I refuse to go above 5.10.

Besides, it results in the same type of behaviour:

use warnings;
use strict;
use feature 'say';

use constant STEPPER_SEQUENCE => [
        [qw(1 0 0 1)],
        [qw(1 0 0 0)],
        [qw(1 1 0 0)],
        [qw(0 1 0 0)],
        [qw(0 1 1 0)],
        [qw(0 0 1 0)],
        [qw(0 0 1 1)],
        [qw(0 0 0 1)],
    ];

use constant STEP_COUNT => STEPPER_SEQUENCE->@*;

say STEP_COUNT;

Output:

ARRAY(0x17985b8)ARRAY(0x17981f8)ARRAY(0x17c8e68)ARRAY(0x17edc90)ARRAY(

Besides, it results in the same type of behaviour: In list context, yes, but like `@{...}` you can force it to scalar context: `0+STEPPER_SEQUENCE->@` is `8`. And BTW, there is also `STEPPER_SEQUENCE->$#` which will returns `7`. tybalt89's code forced the scalar context with the dot `.` operator.	[reply] [d/l] [select]
