Scratch pad for stuff to do before merging master
=================================================
labeled break from a block
better behavior for implicit casts. for example these introduce an extra allocation/memcpy:
var x: [1]i32 = [_]i32{1};
var x = ([1]i32)([_]i32{1});
whereas this one does not:
var x = [_]i32{1};
but all 3 should be semantically identical
This example has less than ideal LLVM IR:
```zig
export fn entry() void {
_ = mul(true, 1) catch undefined;
}
pub fn mul(c: bool, answer: i32) error{Overflow}!i32 {
return if (c) error.Overflow else answer;
}
```
It creates an unnecessary stack variable.
