> The parser must be able to handle absent values in input and translate that into {{null}}
as required. I see several tickets on this matter in the history, but none seem to have addressed
the issue, at least not for parsing. 
> For this problem, I see a need to introduce a new term:
> Definition: _Absent value_ is when there are zero characters between field delimiters.
> Specifically the aim is to be able to parse the following:
> {noformat}
>     "John",,"Doe"    // 2nd element is absent
>     ,"AA",123        // 1st element is absent
>     "John",90,       // 3rd element is absent
>     "",,90           // 2nd element is absent (1st element isn't)
> {noformat}
>  
> See also CSV-93 which I think never addressed the issue, probably because the reporter
was happy with having the issue fixed for CSV output, not for parsing.
> A PR is coming...
