How to deny default scope for ActiveRecord entity

Question

I've created few scopes for my ActiveRecord entity and I want to enforce user using one of it. Is there a way to, say, throw an exception, if no named scope is selected. I.e., I want to dissallow this:

Entity.all

but allow this:

Entity.user(current_user)

Thanks

Override the :all scope

scope :all, #something like throwing an exception or calling other query
