Out of order execution

I haven't even tried pluto precisely because of these worries. I use jupyter+julia heavily (I never "got" jupyterlab but maybe I will give 4.0 a try). Jupyter is both a testing ground for new module functions, and a place to import and run the module. My system is to load the module on the top of the notebook, do testing and development (currently it's a clustering program and I have multiple notebooks open doing different benchmarks), and as and when I write a new function that works and is needed in the module, I put it there. I can also edit existing functions in the module and Revise.jl gets the notebook to "do the right thing" magically.
