That certainly looks very intuitive, and it is similar to what I would
write in an email. The only annoyance is that

And it never will. Note that 100 is not a power of 2, and that the

Ok... I looked up what you did. I see how it works. Thanks.

As covered by Jonathan Lang earlier in this thread (though it was
perhaps easy to miss), Perl 6 auto-detects arithmetic sequences (same
additive difference each time) and geometric sequences (same
multiplicative factor

If you want the index, don't use series. It's easy enough to access the
array elements yourself. You can do something like
my @a :
Hey,
I have a few slightly related questions:
1. The semicolon operator would allow Perl 6 to support N-dimensional
arrays... How would one iterate over that type of array?
my num @matrix[ 10 ; 10 ; 10 ];
I ask because a natural extension is to add arithmetic operators and
you have the beginnin
