[Voted into the WP at the November, 2010 meeting.]
The current wording of 14.6.2 [except.terminate] paragraph 2 makes it sound as if stack unwinding in the case of a noexcept violation is an all-or-nothing proposition. It would be useful to be able to partially unwind the stack, in particular, not to call destructors for the function containing the noexcept-specification.
Proposed resolution (August, 2010):
Change 14.6.2 [except.terminate] paragraph 2 as follows:
...In the situation where the search for a handler (14.4 [except.handle]) encounters the outermost block of a function with a noexcept-specification that does not allow the exception (14.5 [except.spec]), it is implementation-defined whether the stack is unwound, unwound partially, or not unwound at all before std::terminate() is called. In all other situations, the stack shall not be unwound...
