right?

Are there any reason why .byKeyValue doesn't return a Tuple?

There's byPair (http://dlang.org/phobos/std_array.html#byPair) 
that as a library does exactly the following:

```
a.byKeyValue.map!(pair => tuple(pair.key, pair.value))
```

It should be more visible though. Can we include it here:

Or just do it yourself - it's not that difficult:

Well, I didn't have time to fix it then, and I almost forgot about it.
But luckily I kept this thread alive in my mail reader, so here it is:
