-// This package illustrates how basic try-catch exception handling

-// A Handler function handles an arbitrary exception value x.

-type Exception struct {

-// Try invokes a function f with a Handler to throw exceptions.
-// The function f may terminate abnormally with an arbitrary
-// exception x by calling throw(x) within f. If an exception is
-// thrown, Try returns an *Exception; otherwise it returns nil.
-//
-// Usage pattern:
-//
-//	if x := exception.Try(func(throw exception.Handler) {
-//		...
-//		throw(42);  // terminate f by throwing exception 42
-//		...
-//	}); x != nil {
-//		// catch exception, e.g. print it
-//		fmt.Println(x.Value);
-//	}
-//
-// Alternative:
-//
-//	exception.Try(func(throw exception.Handler) {
-//		...
-//		throw(42);  // terminate f by throwing exception 42
-//		...
-//	}).Catch(func (x interface{}) {
-//		// catch exception, e.g. print it
