+title: Support `OverloadedRecordDot` in Haskell Language Server
+---
+
+[Haskell Language Server][hls] (HLS) has support for many GHC language features,
+but new ones (particularly ones that add syntax) sometimes require additional work.
+Currently HLS does [not](https://github.com/haskell/haskell-language-server/issues/2732) 
+have good support for `OverloadedRecordDot`, introduced in GHC 9.2.
+
+The following improvements would bring us up to a reasonable level of support:
+
+- Hover information for fields accessed through dot notation.
+- Completions for record fields after a dot.
+
+Once this is completed, more advanced support could be provided:
+
+- Completions for [virtual record fields](https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/exts/hasfield.html#virtual-record-fields).
+- Code actions to rewrite non-dot-using field accesses into dot-using field accesses.
+- More as inspiration strikes.
