I want to catch exception from async. Shouldn't get() call wait() internal ?  Does i need call wait() explicit before get()?

#include <future>
#include <iostream>
#include <exception>

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
	auto f = async( []{throw exception("err") ; });
		// f.wait(); // Can't catch exception if comment this line. Is it a BUG ???
	catch(const exception& e){ cout << "catched: " << e.what() << endl; }

	return 0;
