- Enum values now can have attributes.
- Generic functions as function parameters are now supported: `fn f[T](x T, i int, f_ Fn[T]) T { `.
- Anonymous structs can no longer have attributes.
- Allow fixed array returns.
### Breaking changes
- `byte` deprecated in favor of `u8` (`u8` is automatically converted to `byte` by vfmt).

### Checker improvements/fixes
- Disallow `Result` type aliases (`type Foo = !Bar`) and `Result` in maps (`map[key]!Type`).
- Add a missing check for taking address of literal value member.
- Fixed map initialization for maps with option values.
- Allow `a << none`, where `a` is `[]?&int`.
- Disallow multiple `else` branches in a match.
- Fix index expression with sumtype of array types.
- Remove hardcoded check for function calls for `C.stat`, `C.sigaction`, etc.
- Fix multiple embedded external module interface.

- Fix alias to struct ptr on struct init.
- Sumtypes can no longer hold references.
- Fix a bug checking generic closures.
- A hard to reach limit of 1 million iterations for resolving all generics.
- Fix missing check for unwrapped shift operation.
- Fix enum max value validation.
- Add a missing mutability check for `array.delete` calls.
- Disallow `_ = <- quit`.
- Disallow type matching with primitive vars.
- Warning instead of error for unnecessary brackets in if/match.
- Include import aliases when checking for import duplicates.
- Fix infering generic array type in nested call.
- Allow casted `enum val` and `const` as fixed array size.
- Disallow multiple return values in const declarations.
- Fix contains() with array of interfaces.
- Disallow mut for blank idents.
