C++ Variadic template AND and OR

Can you use C++11 variadic templates to complete /* ??? */ in:

template<bool...v> struct var_and { static bool constexpr value = /* ??? */; };

so that var_and<v...>::value provides && over the boolean pack v at compile-time?

Can you do the same for struct var_or<v...> for ||?

Can you use short-circuit evaluation (in both cases)?

Edit: An update to the accepted answer added that C++17 fold expressions enable

template<bool... v> constexpr bool var_and = (v && ...);
template<bool... v> constexpr bool var_or  = (v || ...);

It seems that, for parameter pack-based approaches, only a restricted type of "short-circuit evaluation" is possible: while instantiating var_or<true,foo(),bar()> only calls || once, it also calls both foo and bar.
