While

The syntax for while loops is absurdly easy. All you need is the while keyword with some parenthesis and an expression.

while (<expression>) {
    // Do something? Maybe? If you want, I guess?
}

The only real requirement is that the expression type is a boolean. KSL will give you a nice error if you don’t. If this is a problem, you can always cast to a boolean.

while (bool'127) {
    // This loop will run forever (127 will always cast to true)
}
