That’s about the only thing I find immediately appealing. I wish more mono fonts made the various brackets this strikingly different. They don’t need to look good necessarily, just distinct.
The semicolon and all the brackets look to have a lot more emphasis than they do in many common monospace fonts, which makes a lot of sense if you're designing your font for developers. Same with the 1Il distinction they show off in their graphic, or O0.
It's unusual, but I'd bet it feels nice to work with after getting used to it.
