This package provides a rapid prototyping suite for GHCi that can be used standalone or integrated into editors. You can hot-reload individual running components as you make changes to their code. It is designed to shorten the development cycle during the development of long-running programs like servers, web applications and interactive user interfaces.

It can also be used in the context of batch-style programs: Keep resources that are expensive to create in memory and reuse them across module reloads instead of reloading/recomputing them after every code change.

Technically this package is a safe and convenient wrapper around foreign-store.
