instead of signed integers.
- In Nim identifiers en-dash (Unicode point U+2013) is not an alias for the
underscore anymore. Use underscores and fix your programming font instead.
- When the ``requiresInit`` pragma is applied to a record type, future versions
of Nim will also require you to initialize all the fields of the type during
object construction. For now, only a warning will be produced.
- The Object construction syntax now performs a number of additional safety
checks. When fields within case objects are initialiazed, the compiler will
now demand that the respective discriminator field has a matching known
compile-time value.
