> A great idea came out on Slack about local bindings.
> We could allow injecting services based on type hints on a per service/file basis:
> ```yml
> services:
> _defaults:
> bind:
> BarInterface: '@usual_bar'
>
> Foo:
> bind:
> BarInterface: '@alternative_bar'
> $quz: 'quzvalue'
> ```
>
> This way, `@usual_bar` will be injected in any parameter type hinted as `BarInterface` (in a constructor or a method signature), but only for this service/file.
> Note that bindings could be unused, giving a better solution than https://github.com/symfony/symfony/pull/22152 to https://github.com/symfony/symfony/pull/21711.
>
> As named parameters are usable in arguments, bindings could be usable in arguments too:
> ```yml
> services:
> Foo:
> arguments:
> BarInterface: '@bar'
> ```
~Named parameters aren't supported yet.~
Edit:
> Note that bindings could be unused
Current behavior is throwing an exception when a binding is not used at all, in no services of a file if it was inherited from `_defaults` or in no services created from a prototype.
It will pass if the bindings are all used in at least one service.
