[Omaha.pm] Push/pop and guranteed order?

[Daniel Linder]

Fellow Mongers,

When I push values to an array, am I guranteed that they will be
returned in the same order when I use "foreach"?  Here
is my test code:

#!perl

@CurrentList=();

printf ("Pushing: ");

foreach ("A" .. "Z") {

  push @CurrentList, $_;

  printf ("$_ ");

}

printf ("\nReview:  ");

foreach (@CurrentList) {

  printf ("$_ ");

}

The output of the code looks correct:

Pushing: A B C D E F G H I J K L M N O P Q R S T U V W X Y Z 

Review:  A B C D E F G H I J K L M N O P Q R S T U V W X Y Z 

If not, is there an easy way to create a FIFO (First In, First Out)
array?  I don't want to resort to creating a key/value pair (i.e.
key/value: 1:A, 2:B, 3:C,...,26:Z) and have to sort on the key.

Dan
