Richard Eisenberg live-codes a new extension to the Glasgow Haskell Compiler, demonstrating GHC's parser, renamer, and type checker.
This live-coding session will witness a brand-new (mostly useless) extension to GHC. By watching, you will get a road map of how this is done and what the moving pieces in GHC's front end are: parsing, name resolution, type checking, and error messages.Why it's here

On “How to make new Haskell language extensions?”
The first step is creating a proposal for a new extension, which goes through a community discussion https://github.com/ghc-proposals/ghc-proposals/pulls.
Once accepted, the proposal can be implemented in GHC. If you'd like to see how that's done, this is a good demonstration: link to this video
