I’d combine them; but make sure you add a Note explaining the purpose of the extra fields is.  Maybe you can use the same Note

Subject: Re: API Annotations for pragmas

I already have an open diff in D538, covering haddock doc changes for the API annotations, and bringing in a `SourceText` field for HsTyLit.

Should I include the changes for SourceText in pragmas in D538, or create a new one?

It seems that pragma definitions in source are not only case insensitive, but can accept UK or US spelling variants.

I am going to need to capture SourceText values in the tokens, and bring them through into the AST.
