in reply to determining length of multidimensional arrays

Or you can just access the length of the array directly instead of forcing it with scalar context, though this admittedly does return n - 1 instead of n, due to Perlish oddness. 
my @arr = (0,1,2);
my @nested = (3,4,\@arr);

print $#{$nested[2]};

    Or also due to the same Perl oddness OP could:

    my @arr = (0,1,2);
my @nested = (3,4,\@arr);

print scalar @{$nested[2]};

    Prints:

    3
