Wow, how can pairwise tell where the end of 1st array is? There was always the problem feature that regardless whether you write 
my @array1 = (3,4,6,5,8);
my @array2 = (2,2,4,5,1);

or 
my @array1 = (3,4,6,5,8,2,2,4);
my @array2 = (5,1);

[download]
using it with coma always results in flattened list: 
@array1,@array2

[download]
is equivalent to 
(3,4,6,5,8,2,2,4,5,1)

[download]
and yet pairwise deals with it: 
c:\>perl -le "use List::MoreUtils qw/pairwise/; @a=(1..5);@b=(11..15);
+ print for pairwise {$a+$b} @a, @b"

c:\>perl -le "use List::MoreUtils qw/pairwise/; @a=(1..5, 11,12);@b=(1
+3..15); print for pairwise {$a+$b} @a, @b"
