Hello.

On the page "i18n API" I was expecting more guidance on how to use the i18n API. Or at least a mention of its limits as I have been pulling my hair out trying to google how to write common localization with it.

Example 1: Pluralization:
"No Blogs | One Blog | {num} Blogs"

Example 2: Named Formatting:
"Page {num} of {total}"

As it stands I have not found any documentation on whether or not these are possible, so I'm assuming they're not. My suggestion is to add this functionality or at least make a note somewhere in the guide that this functionality is unavailable. 
If you choose to implement these features, here's a fantastic example of documentation of this sort of thing: Vue i18n
