Tracking issue: #149226
This adds support for writing
const { ... }as an item in a module. In the current implementation, this is a unique AST item that gets lowered toconst _: () = const { ... };in HIR.rustfmt support included.
TODO:
pub const { ... }does not make sense (see Add warn-by-default lint for visibility onconst _declarations #147136). Reject it. Should this be rejected by the parser or smth?_ident).
