We use a Kotlin scripting variant for our own shell scripting needs at Hydraulic, it's pretty nice because we've joined it with a lot of internal APIs that make working with the filing system and network easy. It fits all those requirements and more (you can declare flags easily at the top level, it has built in progress tracking for slow operations etc).
The Kotlin type system is comparable to Rust without the borrow checker. It has non-null types, generics, etc.
It's not really a "product" per se but there's an old version for download and some lightweight docs here:
We've never worked out what to do with it. Ideas and feedback welcome. It's pretty nice to use, albeit you need to use IntelliJ to edit scripts if you want IDE features.
