I'm not interested in regexps as I'm not working with strings. This is being used to update database fields, so unless you're doing some really fancy tie-ing, regexps aren't gonna fly :)

For reference, the heart of the code that uses this snippet looks like this:

my $db = DBI->connect( $DSN, 'user', 'sekret', {AutoCommit => 0}) or die "Couldn't connect to database $DSN: ${\DBI->errstr}\n"; END { $db and $db->disconnect } my $ss = $db->prepare( q{update t set department = ? where department += ?}); die unless $ss; my $ok = 1; REPLACE: for my $r( @order ) { for my $key( keys %$r ) { print "$key -> $r->{$key}\n"; if( !$ss->execute( $r->{$key}, $key )) { warn "cannot update $key to $r->{$key}\n${\$ss->errstr}\n" +; $ok = 0; last REPLACE; } } } $ok ? $db->commit : $db->rollback;

NB: The above code is condensed from production code. I have excised things that have no relevance to the example, so it just may or may not compile :)


print@_{sort keys %_},$/if%_=split//,'= & *a?b:e\f/h^h!j+n,o@o;r$s-t%t#u'
