or add something like

struct __type__
{
__type__() { set_current_exception( true ); }
~__type__() { set_current_exception( false ); }
};
#define BOOST_REGISTER_EXCEPTION __type__ __a__;
try{ ... }
catch( ... )
{
assert( !has_current_exception() );
BOOST_REGISTER_EXCEPTION();
assert( has_current_exception() );
...
}

std::uncaught_exception?

Replying to steven_watanabe:

std::uncaught_exception?

It's already catched exception, because we can use boost::current_exception() only in catch block.

What is the motivating case for this feature?
