12:07 PM Ruby Feature #6012: Proc#source_location also return the column

Note that there is also an idiom like `foo(*obj.source_location)`, not just `source_location.last`. By checking the result of "gem-codesearch", we see not only `@binding.source_location` but also `@proc.source_location`. I am not sure if... mame (Yusuke Endoh)
