Boost.Function variant needed

Hi,

For most applications, one wouldn't care that the constructor of
boost::function<> might throw an exception. In my case, however, I need to
ensure that it won't. I think I understand why dynamic allocation is
neccessary to boost::function, but I think there's a wide class of
applications for which it shouldn't be neccessary. I'm thinking of
operations which need to use a function object, but don't need to store it
(think for example of a suite of algorithms operating on a particular type
of iterator).

How far is boost::function from being able to provide this sort of
functionality?

Thanks,
Dave
