Arguably the extra {} around each vector element in the new
initializer syntax is more readable than the proposed assign
v2 syntax.  Tuple and deque support initializer list as do
all classes with constructors and structs.
For what it's worth, your particular example doesn't work in gcc 4.5
because the relevant constructor of std::tuple's is explicit (I wasn't
aware of this effect of marking a constructor explicit, and I'm quite
surprised...).  The analogous example with std::pair works fine.
Yep.  You have to use

v_ v1{
    { "a", 1 },
    { "b", 2 },
    { "c", 3 },
    { "d", 4 },
    { "e", 5 },
};
