resizeable arrays: T[new]

Why would you need it to implicitly cast to a static array?  So you can 
initialize things like "char[4] = "abcd";" ?

// cannot implicitly convert expression (["hi","bye"]) of type char[][2] to 
char
// auto a = ["hi", "bye"];

// works
auto a = ["hi"[], "bye"];

int[char[]] aa;

// cannot implicitly convert expression ("bye") of type char[3] to char[2]
//aa = ["hi":1, "bye":2];

// works
aa = ["hi"[]:1, "bye":2];

typeof(T[0]) foo(T...)()
{
    return T[0];
}

// Error: functions cannot return static array char[2]
//foo!("hi")();

// works
foo!("hi"[])();

Templates also have to deal with static array types in completely different 
ways, since they can't be returned and their .init is not the same type as 
them.
