I've been working on some "documentation" for my own language (see here), which got me thinking: do we all see languages the same way? I personally look for unification of concepts and extensibility in a design, yet I've seen those who care deeply about functional purity or clean decompositions.
What do you look for in a programming language? And why?

I made the anna programming language for a Language Jam I hosted in the beginning of August. 1 week is not enough time to explore too many ideas but 2 interesting(ish) ideas I explored were

1. all function invocation is infix with . (dot) operator. This lets you chain/pipeline nicely.
2. the only looping semantic available is the iterate operator which produces a stream.

I made a playground if anyone wants to poke at it. https://jzwood.github.io/langjam2/submissions/anna/playground/
