Re^2: Assign result of map to scalar variable

... map will output a value for each input value it receives. If there is a match, $1 is returned. If the match fails, the value of the last expression evaluated

Not if you return an empty list (). The usual idiom is this:

my @map_some = map { /foo(bar)baz/ ? $1 : () } @all;

(However, I'm apparently having a Copy/Paste-challenged day, so if you read my node within the first few minutes, it still would have had the OP's if conditional rather than the one I tested.)
