I have a database table with simple text values in it for given keys. I'm tie-ing that table using Tie::RDBMS. So I have a %dbhash containing these values. I have another table that contains what I'll call perl-strings. That is, they are strings, but could look like "Hello, $dbhash{name}, We're sending you your new $dbhash{prize}.". I've tied this table to a hash using Tie::RDBMS as well, so let's say %to_interpolate holds this information. I'm looking for the most efficient way to basically do: 
my %interpolated = ();
foreach (keys %to_interpolate) {
  $interpolated{$_} =  eval "qq/$to_interpolate{$_}/;";
}

I know, however, that eval on strings is relatively slow, so I'm wondering if there's a more efficient way to do this. I really don't need all the power of eval as I'm just trying to interpolate variables, but I haven't been able to do this by other means.
