- That is correct.
-
- >Is there any published material regarding usage of this form?
-
- As far as I know, only the draft standard. This new form of try-block
- was introduced to solve the problem of exceptions thrown during
- member or base initialization, before the body of the constructor
- is entered. Previously, there was no way to find out if any such
- exceptions occurred or deal with them.
-
- >Are there any compilers that support this form?
-
- I don't know which ones support it yet, if any. Eventually all will.
