Would this be worth exploring adding to std?

First, this crate is awesome. I feel like Rust's error story is starting to feel really ergonomic.
This crate looks like a very nice Error type to reach for when working with a leaf/application crate.

Have you thought about working towards adding it to std ?

• anyhow::Error could be added as std::error ( as a pseudo-primitive ) via the same hack that i32 and std::i32 are merged
• std::error could be a very good default for various Err, Error, and E type parameters
• std::error in a future edition could be added to the prelude as just error

I am open to that, but since this crate just came out yesterday it's a bit early to say. I think if we still think this is the best possible approach after ~12 months then that could be good justification for a std::error RFC.

Bumping as it's been 14 months (making "later" now) since the above comment. I do feel like this is the best possible approach to Rust error handling. How should exploring adding to std proceed if it is still viable?

RFC 2820 has some discussion on a standard type erased error type.

There is also now an error handling project group (https://github.com/rust-lang/project-error-handling) whose purview such a proposal would be under.

The error handling project group clearly knows about this crate, so I don't think I need to keep this issue around. Closing and will leave it to them as far as what goes in std.
