The following code is surprising me in two ways:

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

use constant FL  => 17,3,16;
use constant FL2 => 22,4,13;

my @row= "a".."z";
my @a = (" ") x 26;

@a[17,3,16] = @row[22,4,13];

say "@a";

@a = (" ") x 26;

@a[FL()] = @row[FL2];

say "@a";

It seems like constant folding isn't happening at all!!!

I get a warning for FL2
Scalar value @row[FL2] better written as $row[FL2] (ignoring that its a constant _list_)
Deparsing the code shows that FL and FL2 are called as functions
@a[FL()] = @row[FL2()];

Am I missing something?

(This is perl 5, version 16,)

Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
