You could use my DynScalar module (found on CPAN):
use DynScalar;
my $domain;
my %hash = (
offline => dynamic { "$domain is offline" },
busy => dynamic { "sorry, $domain is too busy" },
# ...
);
for $domain (qw( foo.com bar.net )) { print $hash{busy} }
Or, cheat a bit:
my %hash = (
offline => "%s is offline",
busy => "sorry, %s is too busy",
);
for my $domain (qw( foo.com bar.net )) {
printf $hash{busy}, $domain;
}
OOH! Cheating using printf format strings! You like? I like.
