The future use for this will be to allow calling methods/functions/macros from 2015 edition code in 2018, where some additional keywords have been reserved. For example if you are using a crate with "dyn" as a method name then from 2015 you can call it via some_crate::dyn() but in 2018 you couldn't, since it's a keyword, but you could use some_crate::r#dyn(). That's the primary intent for this addition, though I believe some other use cases might be available as well. |
