I would think so.
I wanna know what happens if I do:

Yup, you're right, I didn't consider

Of course.
I tend to agree, I think. But see

I don't think so.
If you've created two separate arrays that happen to start with related

This seems right to me. It would take approximately no time to get
used to this semantic, IMO.

Wow, I wasn't paying attention to what I was thinking there.
Obviously it points to specific elements, because the subscripts used
to create a slice don't have to be sequential

I fear that this might take a reference to each element in the slice,
rather than a reference to the slice
Yes, that would indeed return a list of refs in perl5. Can it also be

Will it be possible (or sane even) to bind a variable to an array slice
e.g
## correct syntax?
my @array = a list of values ;
my @array_slice := @array[ 1 .. @array.end ];
Or would this merely bind @array_slice to the list returned by the slice,
or would it DTRT (in my eyes at least) and
