The packages-first attitude feels significant to me. A language that “users” enjoy but package developers also enjoy seems important. I hadn’t thought about language choice from a heavily package-development weighted perspective before. It seems obvious in retrospect though, which is probably a sign of something cool.

A version of this would be: how can good package development be as easy as possible, and how can package use be as easy as possible?

I haven’t done any serious work in Julia mainly because the python libraries are mature, good, and performant enough. I can’t speak for everyone, but for end users in science labs library support is perhaps the biggest consideration for language choice.

It is.

Many of the language flamewars we do, tend to skip over the eco-system.

Which is much more relevant that any language design issue.

Specially given that the decision of choosing a language is a consequence of working with a specific tool, unless one is open to face some hurdles.
