133. Exception specifications and checking

Section: 14.5  [except.spec]     Status: dup     Submitter: Daveed Vandevoorde     Date: 25 June 1999

14.5 [except.spec] paragraph 1 says,

An exception-specification shall appear only on a function declarator in a function, pointer, reference or pointer to member declaration or definition.
This wording forbids exception specifications in declarations where they might plausibly occur (e.g., an array of function pointers). This restriction seems arbitrary. It's also unclear whether this wording allows declarations such as 
    void (*f())() throw(int);  // returns a pointer to a function
                               // that might throw "int"

At the same time, other cases are allowed by the wording in paragraph 1 (e.g., a pointer to a pointer to a function), but no checking for such cases is specified in paragraph 3. For example, the following appears to be allowed:

    void (*p)() throw(int);
    void (**pp)() throw() = &p;
