// Test the option type in PascaLIGO

type foobar is option(int)

const s : foobar = Some(42)
const n : foobar = None

function assign (var m : int) : foobar is
  block {
    var coco : foobar := None;
    coco := Some(m);
    coco := (None : foobar); //temporary annotation added until type inference
  } with coco
Add purpose comments to some test contracts Add comments explaining what a contract is/does/tests to the top of several PascaLIGO test contracts, as part of evaluating what parts of the syntax are and aren't currently tested. 2019-09-21 14:59:48 -07:00			`// Test the option type in PascaLIGO`
