#9628: Add Annotations to the AST to simplify source to source conversions -------------------------------------+------------------------------------- Reporter: alanz | Owner: alanz Type: feature | Status: new request | Milestone: Priority: normal | Version: 7.8.3 Component: Compiler | Keywords: Resolution: | Architecture: Unknown/Multiple Operating System: | Difficulty: Unknown Unknown/Multiple | Blocked By: Type of failure: | Related Tickets: None/Unknown | Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by simonpj): Whoa! There appear to be two quite separate things going on here: * In [wiki:GhcAstAnnotations] the issue is attaching a `SrcSpan` to keywords * In comment:1 the issue appears to be about attaching an annotation of client-specified type to every node in the tree. These seem quite orthogonal to me. For the latter I would suggest looking at the `Located` type, instead of what you suggest in comment:1. The `Located` type is wrapped around almost every node in the tree, and if you want to add some ubiquitous annotation type, it would be the place to do so.
