I have this list that is basically what a List::MoreUtils mesh or zip output of a list would look like.

Looking all over there doesn't seem to be an unmesh or unzip function out there and my attempts look ugly. I know how many list were zipped into the input, so 
my @test1 = qw( 1 1 2 2 3 3 4 4 5 5 6 6 7 7 );
my @test2 = qw( 1 1 1 2 2 2 3 3 3 4 4 4 5 5 5 6 6 6 7 7 7 );

#  unzip @test1, we know to make it two lists
my $unzipped = unzip( 2, @test1 );
$unzipped = [
    [ 1, 2, 3, 4, 5, 6, 7 ],
    [ 1, 2, 3, 4, 5, 6, 7 ],
]

#  unzip @test2, we know to make it three lists
my $unzipped = unzip( 3, @test2 );
$unzipped = [
    [ 1, 2, 3, 4, 5, 6, 7 ],
    [ 1, 2, 3, 4, 5, 6, 7 ],
    [ 1, 2, 3, 4, 5, 6, 7 ],
]

Any ideas if "unzip" or "unmesh" exists or an elegant way to implement unzip?
