#10382: Template Haskell quotes should work with stage 1 compiler -------------------------------------+------------------------------------- Reporter: ezyang | Owner: ezyang Type: feature | Status: new request | Milestone: 7.12.1 Priority: normal | Version: 7.11 Component: Template | Operating System: Unknown/Multiple Haskell | Type of failure: None/Unknown Keywords: | Blocked By: Architecture: | Related Tickets: Unknown/Multiple | Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Right now, you must enable the `TemplateHaskell` extension to use quotes, and `TemplateHaskell` is not supported by the stage 1 compiler. But there actually is no good reason why this should be the case: quoting doesn't require any user-written code to be loaded up and run, so it should be doable by the stage 1 compiler. I propose adding a new extension, `Quotation`, which turns on JUST quotation and works with the stage 1 compiler. This will solve len's problem https://github.com/ekmett/lens/issues/496 where they want to rename some syntax using quotation, but don't want break compilation on a stage 1 compiler.
