One random thing that bugs me about Rust's syntax is array initialization. In Go I can initialize an array (or strictly speaking a slice) of structs like this:

    var foo []my_struct = {{"foo", 1, "bar"}, {"foo", 1, "bar}, ...}

This is often useful in tests (where each struct value represents a test case). Rust doesn't seem to offer any similarly compact initialization syntax for arrays or Vecs. You have to write some abomination like this:

    let foo = [MyStruct{a: "foo", b: 1, c: "amp"}, MyStruct{a: "bar", b: 1, c: "fff"}, MyStruct{a: "amp", b: 1, c: "aaa"} ];

Sure, it's more explicit. But even if I add a type annotation to 'foo' specifying the array type, I still have to repeat MyStruct for every member.
