FYI: Idiomatic D would be to avoid allocations (faster!).
An example:

```
auto html = " a,b<br/>1, 2<br/>3<br/> ";
auto rows = 
html.strip.splitter("<br/>").filter!(not!empty).map!(a => 
a.splitter(","));
rows.writeln;
```

If you really, really need a 2d array you can always do so if 
required at the end:

```
auto arr2d = rows.map!array.array;
```

But please keep in mind that you ideally avoid the allocations in 
the first place.
