Sorry it took me so long to answer, but I'm still learning it, so I was hoping someone else would pop in.
My impression/hope is that this is another spot where Smalltalk is like lisp. As a clean language with a simple syntax and clean semantics, it seems like where it shines is malleability. It's a substrate on top of which you build a domain-specific language that's tailor-made to whatever problem domain you happen to be working in.
You could have a look at https://adventofcode.com. I've been solving every puzzle so far and it's a fun way to play around with a new language (at least for the first couple of days).
