For performance, I'd like to pre-compile some regular expressions using the qr// syntax, and store them in a database for later use. Sort of like this: 
my $regex = "the (animals|dogs|cats).+?are ready to eat.";
my $compiled_regex = qr/$regex/;

# store $compiled_regex in a database

# later on, retrieve the $compiled_regex_from_db

my $compiled_regex_from_db = [DBI query and unserialize or thaw?];

my $teststring = "the dogs who are friendly are ready to eat.";
$teststring =~ s/$compiled_regex_from_db/creatures/;

Is this possible? Any better ways to store/retrieve compiled regex?

Also is it possible to pre-compile the replacement part of a s/// regular expression? My regex is always search and replace, and the replacement text often has backreferences.

thanks! Nept
