    In my perfect world, you don't need autoloop at all. The compiler should be able to infer the dimmensions mismatch and do the autoloop itself, and on the way, use multiple CPUs when available and vectorization extensions efficiently....

    If you happen to assign to such a slice, you can overwrite the values.
    That's not exactly true:
    @data  = ('a' .. 'l');
    @slice = @data[2, 3, 5, 7, 11];
    print "@slice\n";
    $_++ for @slice;
    print "@slice\n@data <-- no change!\n";
  • David Mertens commented on PDL features I'd like to see in Perl 6

    @Salvador, I have written quite a bit of autolooping code for PDL using PDL::PP. While I agree that it might be nice for the compiler to automatically figure things out, I have seen many circumstances in which the autolooping behavior is ambiguous, and I needed some way to specify how to autoloop.

    As for the unnamed person talking about assigning to slices, you identify exactly what I want in Perl 6, but not what I meant we have in Perl 5. I was talking about using the slice itself as an lvalue, i.e.

    @data = ('a' .. 'l');
    # Assigning directly to the slice overwrites:

    smls here. (Using stackexchange OpenID since logging in normally is borked right now for me.)

    Type checks against array dimensions/sizes

    This seems to be firmly planned, but not yet implemented:

    ➜ perl6 -e 'sub foo (@a($x, $y)) { ... };'
    ===SORRY!=== Error while compiling -e
    Shape declaration with () is reserved

    Aliasing slices

    The following already works in Perl 6 right now (with Rakudo on MoarVM):

    my int @a = 2, 4, 6, 8; # create a compact native array
    my @b := @a[1, 3];      # take a slice, and bind …
  • Aristotle commented on PDL features I'd like to see in Perl 6

    I think the new refaliasing feature (experimental in 5.22) will allow you to alias slices like so:

    \( @slice[ 0 .. 4 ] ) = \( @data[ 2, 3, 5, 7, 11 ] );

    Obviously it’s ugly to have to count out the LHS slice by hand:

    \( @slice[ 0 .. $#$_ ] ) = \( @data[ @$_ ] )
        for [2, 3, 5, 7, 11];

    That’s quite a mouthful, but at least you can package it up in a function:

    sub alias_slice {
        my ( $src, @dst ) = shift;
        \( @dst[ 0 .. $#_ ] ) = \( @$src[ @_ ] );

    \my @slice = al…

  • therflabs commented on PDL features I'd like to see in Perl 6

    Call me crazy, but I had a freelance gig converting Python numpy/scipy to Perl PDL... And barely knowing Python it was a lot easier to understand than PDL.

    I can see why numpy/scipy has gained a lot of traction.

    I'd like to see P6 PDL to be like numpy/scipy to ease crossover to Perl 6 and lower the entry level for beginners. In my opinion usability and clear documentation for the non-math scholar has hurt what PDL could have been and could be a lesson for PDL Perl 6.
