I just found this ingenious library: https://github.com/tailhook/quick-error
This should remove a lot of boilerplate from error definitions. Just what I was dreaming of. ^^

PS - Found it here: https://this-week-in-rust.org/blog/2015/12/14/this-week-in-rust-109/

BTW - I used cargo-edit from cargo-extras to add this dependency to Cargo.toml. It seems like it rearranged some lines in Cargo.toml. That wasn't intentional, I just noticed it right now.

One limitation of quick_error is its lack of struct-like variants: tailhook/quick-error#5

I prefer named fields (i.e. structs instead tuples) in almost all cases of enum-variants with 2+ fields. I hope this will be implemented in the future in quick_error.

PS: quick-error now supports struct like variants, so this limitation is gone.

Independent of using this library, I suggest we use tuple-like variants whenever there is only one field (new-type pattern), and struct-like variants whenever there are multiple fields.

(and btw, happy new year ^^ 🎆)
