I should say Yes! :-)
BTW, result<F(int)> may be called from deref in case of sequence of rvalues.

Ah, yes. I said about `f` in this thread.

My range zipper is used like this:
Again, I place this simple question:
When at_c return type Sequence of input is:
int&, char, double const&, ...
, how can I create
fusion::vector<result_of<F(int&)>::type, result_of<F(char)>::type, result_of<F(double
