We are all aware of this problem. A couple of years ago, Santiago Viana visited our team and conducted a small usability study of Pharo (while he was studying UX at the time). The sample size wasn’t large enough to be conclusive science, but the friction points he identified felt very real:
For maximum throughput, the kernels/ directory contains native Metal GPU implementations
The de facto tool to create Haskell notebooks is iHaskell. We’ve explored the design of iHaskell before. It is the obvious baseline for Sabela. IHaskell demonstrates that a Haskell notebook can be useful and productive. It also exposes three friction points that strongly shape Sabela’s design:
