That's why I introduced it as a thought experiment.

From a usability (or generally practical) perspective:

Of course expressive error messages are (likely) the best solution. With common, handwritten examples perhaps.

And if your interpreter/compiler understands what you are writing, that is always a plus.

But generally it feels as if especially software development is kind of resistant to invent and introduce new tools to make our work easier.

(This post is in danger to walking into "better UI development tools" territory, so I better stop writing now. :blobcatgiggle:​)
