[Feature request] - Retrieve current scope for translations

Hi,

I think it could be useful to have a current_scope method in the AbstractController::Translation module in order to know the default scope used by the translation method.

I already implemented it in my forked repository. Do you think that it can create a pull request with it ?

Thanks,

Hi,

I kindly up my topic with an implementation proposal:

https://github.com/ishigo974/rails/commit/002349d39080b025cd98d4c99b0ed5f6935d32f7

Maybe current_scope is not the most appropriated name and should be name translation_scope or anything referring more precisely to translation?
