Re: [boost] An extension to boost::variant

...

v = boost::reference_wrapper<foo>(f);

You can also write that as

v = boost::ref(f);

Thanks, I hadn't actually seen the reference_wrapper library before, so didn't look too deeply (just far enough to know that passing the raw object didn't work). So, effectively, I'm proposing a small addition to boost::variant, in some sense 'embedding' the boost::reference_wrapper functionality into it, and applying a little syntactic sugar. Does anybody see any value in this, or is it just me? (In the meantime, I can always use a small wrapper to boost::variant that adds these changes.) Chris
