Hi monks,

Using PDL, there is a conflict with using List::MoreUtils (any) because PDL has already an "any". Prototype mismatch: sub main::any: none vs (&@) at Exporter.pm(...).

Eg: catch $d where any $c (@c) $a is defined at index $c.

#!/usr/bin/perl -w
use strict;
use PDL;
use List::MoreUtils qw(any);

my @a;
$a[5] = 1;

my @b = (0..8);

LOOK: for my $d (0..2) {
    my @c = @b[$d*3..$d*3+2];
    if (any { defined $a[$_] } @c) {
        print "d:$d\n" and last LOOK;
        }
    else {();}
    }

The any sub in List::MoreUtils looks like:

sub any (&@) {
    my $f = shift;
    return if ! @_;
    for (@_) {
    return 1 if $f->();
    }
    return 0;
}

But adding this sub returns an error message. Can't find the way to modify the sub...

Also, is this subroutine optimal (does it looks all elements in the array or does it stops rightaway when the "any" condition is met) ?

Thanks very much for comments and hints, best.
