I think the "issue" is that when you write "[1, 2]", that array 
is still "weakly typed", and the compiler will implicitly cast it 
to any type that will create a match. Once you've crammed it into 
a variable though, it becomes explicitly typed, and the casts 
become no-go.

It's kind of like how you can write:
wstring s = "hello!";

I dare say that the behavior is expected.
