in reply to how is = treated in argument?

In the advice you've already been given a major issue was to figure out what you really want to do.

I guess. Perhaps you want actually something like this?

#!/usr/bin/env perl

use strict;
use warnings;
use Data::Dump;

my $result = func( v => 33 );

dd $result;

sub func {
    my %args = @_;
    return \%args;
}

__END__

{ v => 33 }
