LOL - irrelevance is not a reason to avoid posting here.

But this raises another interesting question.  How about something like:

template<class F, class C>
auto range_adaptor(const C & c){
        return F(c.begin(), c.end());
}

so one could say

vector<int> v = ...

range_adapt(std::find, v);

for any collection type.
