Dear GHC developers,

In recent weeks, John Ericson has fine-tuned a Haskell Foundation Technical Proposal to split `base` into two libraries: `ghc-base` and `base`, the latter simply re-exporting everything for `ghc-base` (for now). You can read about the rationale and specifics more in details in the proposal itself:

Note that this proposal has recently been streamlined into a form which is more focused than its initial state, and might be worth a re-read.

The Haskell Foundation Technical Working Group has reached a consensus that this work will benefit the Haskell community. Moreover, the Haskell Foundation has agreed to spend some of its resources to implement this proposal, which would start by ensuring the completion of MR7898 (

This work will affect GHC developers. Therefore, the Technical Working Group would like to get buy-in from the GHC developers before formally accepting this proposal.

Best regards,
Laurent P. René de Cotret
on behalf of the Haskell Foundation Technical Working Group
