You could always use Tie::IxHash for this. You can also cheat and do what I find myself doing sometimes:
my @pages = (
welcome => \&page_welcome,
address => \&page_address,
recipients => \&page_recipients,
preview => \&page_preview,
done => \&page_done,
);
my %pages= @pages;
@pages= do { my $key= 0; grep { $key= !$key } @pages };
Since you have two hashes with shared keys, you might go a different route like:
my( @pageorder, %pages, %validators );
for(
["welcome", \&page_welcome, undef],
["address", \&page_address, \&validate_address],
["recipients", \&page_recipients, \&validate_recipients],
["preview", \&page_preview, undef],
["done", \&page_done, undef],
) {
push @pageorder, $_->[0];
$pages{$_->[0]}= $_->[1];
$validators{$_->[0]}= $_->[2];
}
or perhaps:
use mapcar;
my( @pageorder, %pages, %validators );
BEGIN {
my( $key, $page, $valid )= mapcar {[@_]}
["welcome", \&page_welcome, undef],
["address", \&page_address, \&validate_address],
["recipients", \&page_recipients, \&validate_recipients],
["preview", \&page_preview, undef],
["done", \&page_done, undef];
@pageorder= @$keys;
@pages{@$keys}= @$page;
@validators{@$keys}= @$valid;
}
Season to taste.
