```d
int[$] arr = [1, 2, 3];
```

It's OK, however:

- Doesn't work as an expression - except `(){ int[$] arr = [1, 2, 
3]; return arr; }()`, which is no better than 
`imported!std.array.staticArray!int(1, 2, 3)`.
- Requires specifying the element type, which may be a 
complicated type

I think the typical case may be not wanting to specify the 
element type. If that is correct, it would be better to have 
syntax for a static array literal. E.g. `[1, 2, 3]$`. So maybe we 
need some data about use cases before picking a solution.

Also I note that `staticArray` would be fine if it was in 
`object` (instead of various uncommon AA functions) so it didn't 
need an import.
