The goal of my Google Summer of Code project was to introduce support of multiple home units for GHC. The main motivation for this proposal is to help IDEs provide a seamless developer experience. Currently, two of the bigger IDE projects in Haskell are ghcide and Haskell IDE Engine. Both of these projects aim to support a workflow where developers can work on multiple packages, such as a package's library and executable at the same time. The work-force behind it is GHC itself, which is responsible for actually compiling a user's source files. While we succeeded to create a fork that implements the proposal, nothing has been merged into upstream yet. This is to be expected, since it is a huge change that will impact a considerable number of the GHC API's consumers. Therefore this feature needs to be designed with care and code changes verified to have no unintended sid
