I mean, Odin is admittedly vastly different from C in terms of syntax. It's not like you can pick it up knowing C, it feels like a different language.
The author even states that Odin started as a Pascal clone, and was more influenced by Pascal than C.
> The language began as a Pascal clone (with begin and end and more)
> The language borrows heavily from (in order of philosophy and impact): Pascal, C, Go, Oberon-2, Newsqueak, GLSL.
Plus if you look at something like Zig, it syntactically starts to drift a lot as well. They left behind C's "use matches declaration" approach (thank God), capture groups look like nothing in C, function definitions are entirely different, the list goes on.
