A Haskell2010 TemplateHaskell syntax library

This is somewhat tangential to your efforts for a revised Haskell2010 report. But for a long time we've wanted to have a stable TemplateHaskell syntax tree library. `template-haskell` must express the entirety of the ever evolving surface syntax and so cannot fulfill that role.

Given the new effort to standarise Haskell2010, I think using the Haskell2010 AST as a target for a `template-haskell-haskell2010` package sounds like a viable goal. Perhaps such an AST could even be part of the standard.

I was wondering if you all had any thoughts about this?

Start by reviewing the proposed Haskell2010 AST target and the existing template-haskell surface syntax. Assess whether a stable template-haskell-haskell2010 package could represent the standardized syntax, and document the project's decision on whether this should be pursued or included in the standard.
