I agree. I think you can remove that extra try/catch.

With all due respect, Python, C#, Java, Rust, and other languages also allow multiple commands on the same line just like ObjectScript does. I see that Go doesn't allow this.

ObjectScript simply evaluates expressions (arithmetic and logical) strictly left-to-right. Using parentheses gives you control, and has the added benefit of making a complex expression easier to read for other developers. Would you ever write this in any language?

if a = 3 && b = 4 && c = 5 || d = 6 {write "succeeded"} else {write "failed"}

No. You'd write it like this:

if (a = 3) && (b = 4) && ((c = 5) || (d = 6)) {write "succeeded"} else {write "failed"}
