- Compile time checks for integer and float conversions are now stricter. For example, `const x = uint32(-1)` now gives a compile time error instead of being equivalent to `const x = 0xFFFFFFFF'u32`.
- A bug allowed ``macro foo(): int = 123`` to compile even though a
macros has to return a ``NimNode``. This has been fixed.
- Using `typed` as the result type in templates/macros now means
"expression with a type". The old meaning of `typed` is preserved
as `void` or no result type at all.
