  [;1m-spec list_to_binary(IoList) -> binary() when IoList :: iolist().[0m

  Returns a binary that is made from the integers and binaries in [;;4m[0m
  [;;4mIoList[0m, for example:

    > Bin1 = <<1,2,3>>.
    <<1,2,3>>
    > Bin2 = <<4,5>>.
    <<4,5>>
    > Bin3 = <<6>>.
    <<6>>
    > list_to_binary([Bin1,1,[2,3,Bin2],4|Bin3]).
    <<1,2,3,1,2,3,4,5,4,6>>
