This is a wrapper macro that supplies:
- simple name-based memoization/checkpointing (note: not @memoize)
- injected logger and ckpts arguments
- invocation of stage functions is asynchronous via
@spawn - results are returned as remote ref of tuple (result, logger-output)
Scripts using stages would ideally run in something like an ijulia notebook. Currently, ijulia notebooks don't handle magics, but eventually, when they do, we can clean up/manage checkpoints via filesystem commands.
Note: Ipython checkpoints provide script versioning but they don't checkpoint execution.
