Hi, I am thinking of an interface that goes in this direction for more than a year now, but I am not there yet. A classic REPL works fine for sequential programs, but the problem with this is that as soon as you do anything meaningful and want to iterate, you get a bit lost.

For example, imagine you demo on a system complexity like visualization using a Mondrian builder: You first do: view nodes: classes. view edgeFrom: #superclass. view treeLayout This can work just great. But, now you need to add at the beginning: view shape rectangle height: #numberOfLinesOfCode You have to start again. The REPL interface was bound by the abilities of a terminal. But, we do not have those constraints anymore, and that interface has to be rethought.

One thing I am thinking of is having groups of text that get a preview. For example, imagine that you see a preview only after you say Cmd+Enter. Now, about your points. You are right in that the implementation of Cmp+p was a nice solution 40 years ago, but now we can do better. There is no need for Cmd+p to affect the current text. This can be solved easily, and it is on the soon to show roadmap. This alone should alleviate the current playground usability.

In a workspace you need to press Cmd-p - In an evaluator, you have the nice highlighting for _each_ entry. In a workspace, everything is messed up after evaluating the first expression - In an evaluator, you have usually pseudo variables to access previous results. In a workspace you cannot do that, else by putting parenthesis everywhere - an evaluator is well suited for demonstration (e.g., the Wolfram language, Light table...)
