No worries, as you can see, I know how it goes 😃

Adding a dedicated option that would specify which entity name should be used can be done relatively easily. I guess it could be called `struct_class`, so ie:

```ruby
belongs_to :identities, as: :by, struct_class: 'Identity'

```

Alternatively we could use an option that would prevent struct inferrer from using the alias.
