The plugin was implemented by calling "load" which circumvents all of HLSs caching mechanisms for interface files and linkables. Instead we should work like the other typechecking functions which get all the stuff we need using HLS rules and setup the HscEnv with all the state in the right places. The key part to this is setting up all the HPT modules with linkables if they are depenedencies of the module we are trying to run a function from.

Would you like to add yourself to CODEOWNERS for this plugin? :) Since it's currently totally unloved. |

There was a problem hiding this comment.
Why is it ok to skip this setup? It was copied from GHCi to try and replicate the same behaviour
