Yes. Read the first sentences in the docs again!

caller: "Returns the current execution stack—an array containing strings
in the form file:line or file:line: in `method'."

caller-locations: "Returns the current execution stack—an array
containing backtrace location objects."

And see:

  2.0.0-p247 :002 > caller_locations.first.class
   => Thread::Backtrace::Location
  2.0.0-p247 :003 > caller.first.class
   => String
