        # Thread::Backtrace::Location.label

(from ruby core)
### Implementation from Location

    label()

---

Returns the label of this frame.

Usually consists of method, class, module, etc names with decoration.

Consider the following example:

    def foo
      puts caller_locations(0).first.label

      1.times do
        puts caller_locations(0).first.label

        1.times do
          puts caller_locations(0).first.label
        end

      end
    end

The result of calling `foo` is this:

    label: foo
    label: block in foo
    label: block (2 levels) in foo
