While Loop
while
loops follow C syntax.
Like C, continue
can be used to skip to the next iteration, by-passing all following statements;
break
can be used to break out of the loop unconditionally.
`while` loops can be disabled via [`Engine::set_allow_looping`][options].
let x = 10;
while x > 0 {
x -= 1;
if x < 6 { continue; } // skip to the next iteration
print(x);
if x == 5 { break; } // break out of while loop
}
