Wherein I call on the perl monks to aid me in my misguided quest to reduce some perfectly understandable, and fairly minimal code into a one-liner.

Given the following code, which uses a hash find the unique things in a list of such,

my %this_to_that = map {$_->this => $_} @things;
return values %this_to_that;

How does one obviate the need for the temporary (named) hash? I naively expect something like the following to work, but does it does not.

return values %{map {...} @things}

Type of arg 1 to values must be hash (not anonymous hash ({})) at...

Is it possible to do this with an anonymous hash?
