  propertyWithAnExceedinglyLongName7: string;
  propertyWithAnExceedinglyLongName8: string;
};
 
// String representation of type of 'x' should be truncated in error message
var s: string = x;
Type '{ propertyWithAnExceedinglyLongName1: string; propertyWithAnExceedinglyLongName2: string; propertyWithAnExceedinglyLongName3: string; propertyWithAnExceedinglyLongName4: string; propertyWithAnExceedinglyLongName5: string; propertyWithAnExceedinglyLongName6: string; propertyWithAnExceedinglyLongName7: string; propert...' is not assignable to type 'string'.
