Re: qw() and lists of lists

my @nametape = (
    [qw( 24 101 )],
    [qw( 25 102 )],
    [qw( 23 103 )],
);

Note three things, though:

You don't need the quotes either way, because these are valid numeric literals.
You do need the square brackets and trailing commas, because...
... there's no such thing as a lit of lists. Lists never nest. I know—it's a nitpicky argument about definitions, but the documentation uses these words very precisely, so you'll avoid at least some confusion if you get in the habit of referring to the different entities known as "list" and "array" in the same way the documentation does.

there's no such thing as a list of lists. Lists never nest. List literals never nest, a list of lists is an array of arrays	[reply]

Can you make a non-literal list of lists which doesn't nest?	[reply]
