In the first snippet, I originally had 'map' instead of 'grep'. 'map' will give back the return value from the s/// operator, which is not the modified string.
(from another follow-up:)
But you missed one aspect in your version: filter { s/a/b/ } @list shouldn't modify the original @list.
In that case, make a copy. And return $_. 
  map { local $_ = $_; s/^[^-]*-//; $_ } LIST
