Call/Return feature of classic C++(C with Classes), what modern languages have it?

问题

On page 57 of The Design and Evolution of C++, Dr. Stroustrup talks about a feature that was initially part of C with Classes, but it isn't part of modern C++(standard C++). The feature is called call/return. This is an example:

class myclass
{
  call() { /* do something before each call to a function. */ }
  return() { /* do something else after each call to a function. */ }
  ...
};

I find this feature very interesting. Does any modern language have this particular feature?

回答1:

The modern C++ equivalent would be a sentry object: construct it at the beginning of a function, with its constructor implementing call(), and upon return (or abnormal exit), its destructor implements return().

回答2:

Aspect Oriented Programming has this. http://en.wikipedia.org/wiki/Aspect-oriented_programming

Aspect Oriented Programming (also known as AOP) has the ability to create interceptors before, after and around code.

回答3:

The D2 programming language has this and more with it's ScopeGuards. It's designed so you can use multiple ones, they work like a FILO stack.
