Cloud Haskell 3.0 Proposal

Discussion

Although I've called this iteration of Cloud Haskell 3.0, this doesn't represent an epoch for any of the libraries - indeed distributed-process is still at v0.7.4 as of December 2018. Instead we're talking about a third re-write, the first iteration being the remote package, and the second being the current live version.

Motivation

See the High Level Redesign Proposal for details.

Outline

The architecture of the current (2.0) release is outlined here.

We will present several viewpoints, starting with a bottom up, dependency oriented perspective.
