## This works around multiple issues:

## - enumerating directories lets us avoid HIE files in other places (like the Direnv cache), since there’s no way

## to exclude directories (ocharles/weeder#201)

## - having ‘.stack-work’ in the explicit path avoids a bug in Weeder where it wouldn’t search through hidden

## directories (ocharles/weeder#190)

## - including the GHC version filters HIE files from other builds (like those in the GitHub CI caches after a GHC

## upgrade)
