Ok, I am bit harsh here, but for me there ARE no other systems languages except C, C++ and recently maybe Rust. I am also told, that in distant lands with strange and foreign customs, Ada is a systems language. (I don't know - no Ada missionaries have yet set foot on our shares and preached it to us.)

>no Ada missionaries have yet set foot on our shares

I'm not sure if 'shares' is a typo or not, but it fits great with my impression of why companies choose the languages they do sometimes: everyone else uses it (it's the local culture/custom), and nothing/no one has forced them to change (by lowering their profits/share value).

It was a typo, should have been "shores". However, it was a brilliant typo - the powers that be have decided on Greenhill and ClearCase. And the people who decide these things seem to be closer to the share holders than they are to us coders, so Ada missionaries on shares is maybe what it takes.

You would do yourself a favour to improve your CS skills regarding the history of computing, maybe you know, get to learn some interesting stuff.

There are YouTube videos....

A really damn good execution.

Which in my mind matters more than all this pedantry.

In what sense do Rust modules provide a better execution over Ada packages?

If we define "the bar" as "people's expectations for what a useable module system looks like" you can set it without being novel at all
