Yes that is a good point, which I had forgotten about in my
concern over syntax.
Some guidance is needed about what the default passing is likely
to be in perl6.
Will
(@x,@y) = mysub @a, @b
implicitly pass by reference?

I see a number of problems with the current (scalar) PDL objects being
turned (essentially) into perl arrays in perl6.
1) How do y
Consider
@x[10:20, 20:40:2, 30:50]
This ALMOST works in the current Perl. @x gives array context,
then the , produces a list.
If [] is overloaded on @a then the subroutine sees a list like
"10:20", "20:40:2", "30:50"
The only reason it does NOT work in the current perl is that "10:20"

Not true, at least not in the Perl I know. :-) Here's a description of
what these do in Perl just to clarify:
$a[0][1][2]; # get a singl

Agreed. We sh
Looks like if we give the data type control over what
the meaning of square brackets after it is, the rest
becomes example code. I think this s covered in the
horribly misnamed http://dev.perl.org/rfc/115.pod which
covers overloading bracketing.

Both of these already have firm meaning in Perl. The second one is used
to bite off selected elements of an array. So if you want a different
syntax you'll have to use some ot
There is already a reshape() in PDL.
Obviously that only applies to PDL arrays.
But if PDL style arrays get in to the core, then that sort of
functionality ought to arise.
OK here is a basic question: how do we specify element access in
PDL type arrays?
$a[$i][$j][$k] or $a[$i,$j,$k]
