[clug-progsig] Perl array disorder

[Royce Souther]

I don't think I would call this a bug but more just another joke Larry Wall
is try to play on Perl programmers.

I am working with a custom config file that looks kind of like badly
formated XML in that each field may contain any number of entries and
sub-entries. I stack the data into an array and when I go to pull the data
back out is is in a different order then when I put it in. This is not a
problem because the oder of the data is not important as long as the
hierarchy remains intact. I would like to know if there is a reason for
this. At some point in the future I may want an array in order and I should
know what needs to be done to make that way.

root at QtCompiler[~] #cat ./PerlArrayDisorder.pl
#!/usr/bin/perl

my @TestArray;
$TestArray->{'1'} = "one";
$TestArray->{'2'} = "two";
$TestArray->{'3'} = "three";
$TestArray->{'4'} = "four";
foreach $key (keys %{$TestArray})
{
        print "key=$key, value = ".$TestArray->{$key}."\n";
}
root at QtCompiler[~] #./PerlArrayDisorder.pl
key=4, value = four
key=1, value = one
key=3, value = three
key=2, value = two
