// make sure literal conforms to type
let var: Type = { 
   prop,
   prop2: 123,
   extra: 'value' // will give an error for extra properties
};


// make sure properties from type are spelled correctly
let var = <Type> { 
   porp,         // will give an error if prop is required in Type, ignored if not
   prop2: 123,
   extra: 'value' 
};

let var = x as Type;  // nice cast without angle brackets, avoids type annotation on var
