You may like Syntax::Feature::Qwa, but it's a pretty heavy dependency unless you're defining a lot of arrayrefs, and really hate typing square brackets.

use 5.010;
use strict;
use warnings;
use syntax 'qwa';

use Data::Dumper;

my @nametape = (
    qwa( 24 101 ),
    qwa( 25 102 ),
    qwa( 23 103 ),
);

print Dumper \@nametape;

If the arrayrefs are just numbers, then map and split might be your friends:

use 5.010;
use strict;
use warnings;

use Data::Dumper;

my @nametape = map [split ":"] => qw(
    24:101
    25:102
    23:103
);

print Dumper \@nametape;
