> Look at the popularity of Jupyter notebooks, Julia, etc. Neither of these (inherently) have the kind of "live programming" environment that the original comment was talking about. Jupyter notebooks have a different reproducibility problem though, with how easy it is to create hidden state. But they're not intended to be used in production at all anyway, so the problem mainly affects pedagogical and information sharing use cases. Julia with the Revise.jl package installed and loaded comes kinda close to the live programming model - but the state is always preserved in the source file necessarily with Revise (and it's a development tool too, not one loaded in production). Since you mentioned it alongside Jupyter, maybe you meant the Pluto notebook for Julia? There too the state is always preserved, both in terms of packages (with Julia's usual Manifest file) and in terms of your code (no hidden state like Jupyter, since it's a reactive notebook).
