Abstract prioritization

In HL I have the following:

```haxe
package hl

@:coreType @:notNull @:runtimeValue abstract UI16 to Int from Int {}
```

Now the problem is that `UI16 * Int = UI16` while I would like to result to be `Int` since it's a "larger type".
Is there a way to define that kind of priority (without having to define all the binops on UI16) ?

Funny is that `F32 * Float = Float` , so it seems it depends on the core type (or is it unspecified?)
