It might be interesting to try a modified boost::any that uses
<boost/detail/quick_allocator.hpp>.
void * operator new(std::size_t)
{
return detail::quick_allocator<this_type>::alloc();
}
void operator delete(void * p)
{
detail::quick_allocator<this_type>::dealloc(p);
}
needs to be added to any::holder<>.
