Dear GHC devs,

I’m trying to invoke the GHC.Core.Lint linting functions from a Core GHC plugin.
These functions take a LintConfig that can mostly be constructed from DynFlags,
the exception being

l_vars :: ![Var] — ^ Ids that should be treated as being in scope

My question is then “How can I get all variables in scope in the module underlying this CoreM computation, to pass in the LintConfig?”.

My ultimate goal is to run LintM to determine the usage environment of a given core expression.
In that sense, the “Id out of scope” errors aren’t that important to me, but they do make the linting action fail.

Thanks in advance!
Rodrigo
