So you'd prefer writing this:

   boost::any<...> a(...);
   int i(a.template get<int>());

to this?

   boost::any<...> a(...);
   int i(any_cast<int>(a));

The latter has the advantage of looking just like static_cast et
al, avoiding the ugly template qualification of the member
function invocation, and being shorter.

I think the current approach is better.
