in thread improve ugly flow control

I liked that quite a bit, but the structure has been bothering me, like with most other solutions: it feels to me like the failure case gets too much emphasis. I didn't know how to do any better when I first saw the post, though. But now I think I do:

{ my $try = first { $hash{ $_ } } @options; defined $try or ( log_failure(), last ); do_something( $try ); }

Makeshifts last the longest.
