           Summary: std.experimental.allocator.makeArray does unnecessary
                    allocations for ranges with length

           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal

         Component: phobos

makeArray does not use length information for input ranges if it exists,
causing extra calls to malloc.
