I love reading through answers to even "simple" questions because I get to see new ways to solve problems and new syntax. This code is a prime example. Embedding code in a for loop like this is something I've never even thought of, but it makes sense that you can do that.

But, what's with the [ 0 ] at the end? 

my @arr    = ( 3, 4, 71, 1, -598, -100203 );
say for (
   sort { $arr[ $a ] <=> $arr[ $b ] }
   grep { $arr[ $_ ] >= 0 }
   0 .. $#arr
   )[ 0 ];   # okay. what's with the [ 0 ] ??????
