japhy, very neat little code.

Am I allowed to make some suggestions though? I am concerned mainly with what would happen if $record contained a different amount of fields than you specify. If so, then the program will attempt to either use one of the record's values as an array reference (ouch!), or stick a reference of one of your arrays in another (ewww :) ).

So perhaps a little change to your arguments: 

multi_push(
  \(@names, @ages, \@locs) =>
  [split /::/, $record]
);

The first line hasn't changed, we still get 3 references to an array -- \(@a, @b) is shorthand for (\@a, \@b). The second line is only changed in that the array of values is turned into a reference to an array of values.

So how about a rewrite of the code to use the new parameter syntax: 

sub multi_push{
  my @v = @{ pop @_ };
  my @fs = @_;
  for my $f (@fs) {
    push @{ $f }, +shift @v;
  }
}

Or if you like something closer to your code: 
sub multi_push {
  my @v = @{ pop @_ };
  while(@_) {
    push @{ +shift }, +shift @v;
  }
}

Warnings: Not tested, as I don't have the luxury of perl access at work :( :( . (So maybe there are more +'s than necessary :) ).

Welp, have fun.

Ciao,
Gryn
