I also love rust and we use it heavily at our startup, but I agree with you and wish there were a mainstream alternative that kept much of the type system, pervasive expressions, and pattern matching while being smaller. I’d accept “very fast” even if it’s not as fast as rust.

One project I’ve seen that I don’t think is particularly active but that I really like the ideas behind is borgo. It compiles to go (thus GC) but is decidedly more rustacean.

Check it out. I hope someone makes something like this wide spread.

PS. I have no affiliation with borgo, just an online fan.
