I don't like the proposed resolution of 829. The normative text is unambiguous that the exception_ptr refers to the currently handled exception. This term has a standard meaning, see [except.handle]/8; this is the exception that throw; would rethrow, see [except.throw]/7.
A better way to address this is to simply add the non-normative example in question as a clarification. The term currently handled exception should be italicized and cross-referenced. A [Note: the currently handled exception is the exception that a throw expression without an operand ([except.throw]/7) would rethrow. --end note] is also an option.
