I think it&#x27;s a shame that so few people these days know what a smalltalk development environment looks and feels like. There is no distinction between learning and experimenting. It&#x27;s all part of the same feedback loop. It&#x27;s a shame that almost no modern programming language these days provides the same kind of workflow. If they did I think the author would have a different take on learning and experimenting all in one go instead of segmenting things the way he did.
