# Description ## Problem\* Resolves #4586 Part of #4594 ## Summary\* Adds a `quote { ... }` expression to the parser along with a new builtin `Code` type which it is the only method of creating. ## Additional Context The quote expression can only currently quote expressions and statements. It cannot yet quote top-level statements - we'd need more parser changes for this. In particular the top level statement parser would now need to be recursive and passed down all the way to the expression level... Trying to use `quote` in a program gives you an `experimental feature` warning. Indeed, the only thing you can do with it currently is panic once it gets to monomorphization without being removed from the runtime program yet. ## Documentation\* Check one: - [x] No documentation needed. - I'm following the pattern with other experimental features and waiting to document them until they're stable. For this, it means quote won't be documented until the base for metaprogramming is completed. - [ ] Documentation included in this PR. - [ ] **[Exceptional Case]** Documentation to be submitted in a separate PR. # PR Checklist\* - [x] I have tested the changes locally. - [x] I have formatted the changes with [Prettier](https://prettier.io/) and/or `cargo fmt` on default settings.
