throws keyword for methods and constructors declarations

[AAAbramenko]

What is about to introduce throws keyword:

String readDataFromFile(String path) throws IOException, FormatException {
...
}

This will help to indicates that place of method/constructor calling must be wrapped in try-catch block.
You can find same language feature in Java (look spec here and here)..

Isn't this the same as checked exceptions? If yes, duplicate of #984.

Yes, what you're looking for is checked exceptions. We have discussed it at length but feel it's not an overall win for users.
