hello
A program without a profile attribute is native: jihoo run compiles it with
LLVM and runs it. With #![hosted] at the top it would run on the VM instead.
jihoo run examples/hello.jhfn greet(name: str) -> str { return "Hello, " + name + "!"}
fn main() { print(greet("jihoo"))
let i = 1 while i <= 5 { print(i * i) i = i + 1 }}
