Statements

Closures in Knot can be empty or contain one or more statements.

Expression​

Any expression is a valid statement.

knot
func foo -> {
  10 + 0.4;
  true && false;
  "fizz" == "buzz";
};
knot
func foo -> {
  10 + 0.4;
  true && false;
  "fizz" == "buzz";
};

Let Binding​

If a let binding is the last statement in the closure then the return value is implicitly nil.

knot
func foo -> {
  let bar = 10;
  let fizz = bar - 3 > 10;
  let buzz = !fizz;
};
knot
func foo -> {
  let bar = 10;
  let fizz = bar - 3 > 10;
  let buzz = !fizz;
};
