The new nested meta parsing APIs are pretty nice, but `syn::meta::parser` returns a `impl Parser` and does not compose very well with other parsing code. How about making `syn::meta::parse_nested_meta` public?...

Could you please update the release notes to describe change 5036fd9c6e9b89809f93a6ffa17ac6663652baed ? It caused mockall to fail in some cases, and I was surprised to see a breaking change missing...

I struggled for quite a while to understand how to deal with the position field of the `syn::QSelf` type. I understand that as an author it is difficult to see...

Add `Item::attrs` to get the attributes of an item if available

1

Hello, thanks for the crate! When looking at `Item` I was surprised not to find APIs that ease its use, without having to pattern-match every time, like for [`rustc_hir::ItemKind`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_hir/hir/enum.ItemKind.html). This...

Here is syn's current RangeLimits enum: https://github.com/dtolnay/syn/blob/391c9c6d1667be37cd5ad4de5fa305ec62296bb8/src/expr.rs#L904-L909 Rustc has the exact same thing: https://github.com/rust-lang/rust/blob/1.67.0/compiler/rustc_ast/src/ast.rs#L1323-L1328 ```rust pub enum RangeLimits { /// Inclusive at the beginning, exclusive at the end HalfOpen, ///...

Consider whether const generics supersedes the `Token!` macro

3

Something like: ```rust pub struct Token; ``` Then you'd use `Token` for what used to be `Token![+]`, and `Token` instead of `Token![+=]`, etc. The `custom_punctuation!` macro (https://docs.rs/syn/1.0.105/syn/macro.custom_punctuation.html) would no longer...

Using new Span diagnostics

1

I'm trying to figure out how to effectively use the new Diagnostic API in lieu of the `Parse` trait's `Result` type, which only emits the old spanned `compiler_error!()` trick. In...

In my use case I'm providing a library that helps with parsing a specific kind of token stream syntax, namely something HTML/JSX-ish: [`syn-rsx`](https://github.com/stoically/syn-rsx). I'd like consumers of the library to...
