I was reading the Macro Changes page:

Note that you'll still need #[macro_use] to use macros you've defined in your own crate; this feature only works for importing macros from external crates.

A couple questions that immediately came to mind:

  • Why? Could a link be added for people to read more about this?
  • Is it planned that in the future you can import macros from your own crate?

I think it would be helpful to add a little background about this, as I'm sure others will have similar questions.
