> Here is an example:
> Data input:
> {code}
> 1       1
>         2
> {code}
> the script 
> {code}
> a = load 'input';
> b = load 'input';
> c = join a by $0, b by $0 using 'repl';
> dump c; 
> {code}
> generates results that matches null values:
> {code}
> (1,1,1,1)
> (,2,,2)
> {code}
> The regular join, on the other hand, gives the correct results.
