@nojaf , Hey mate while doing a merge I noticed this: https://github.com/dotnet/fsharp/blob/823f7d5c55245954f468f1b239a189c3b88af34b/src/Compiler/SyntaxTree/SyntaxTrivia.fs#L322 [<NoEquality; NoComparison>] is missing from : type SynTypeOrTrivia = { OrKeyword: range } Is that intentional, or an oversight? Thanks Kevin
