There isn't a "good" way to do this. The only way I know is:

```d
a1[0] = 0;
a1.clear();
```

This will leave an empty, but allocated AA.

It would be pretty trivial to add this feature (make me an empty but 
allocated AA). Probably 2 lines of code in druntime. People have tried 
in the past to allow reserving memory for an AA, but it's not a trivial 
task (unlike this).

I think there is an issue report somewhere, let me see... No didn't find 
one.
