Okay. But fix the "http://www.boost.org/more/error_handling.html", please.

Subject: std0X::expected_exception<T>()
"....
template<class T> bool expected_exception() throw();
Returns: true if matching handler is found.
Notes: if expected_exception<T>() returns false then
throwing T (at the point of expected_exception<T>()
invocation) will result in the invocation of unexpected()
handler with an exception consider caught. In effect,
(in this new edition of this International Standard:-)
if (!std::expected_exception<T>()) {
throw T(/*...*/);
}
is equivalent to:
if (!std::expected_exception<T>()) {
try {
throw T(/*...*/);
}
catch(const T&) {
std::unexpected();
}
}
...."
Would you vote against it? Why?
TIA.
