In writing GHC plugins, how can I (a) add a module import (preferably qualified) and (b) make vars/ids for names imported from the newly imported module (to insert in the transformed Core code)?<br>
<br>
If it's not possible to do what I want, I'd be willing to require an explicit import (say "import qualified Foo") in client code, as a temporary workaround.<br>
So far I've been unable to import even from the base package. Maybe I'm missing something basic that you folks have learned.<br>
<br>
My simple & unsuccessful attempt is at <a href="https://github.com/conal/plugin-import-id" target="_blank">
