13. Other Changes
========================================
- Core:
. The iterable type is now a built-in compile time alias for array|Traversable.
Error messages relating to iterable will therefore now use array|Traversable.
Type Reflection is preserved for single iterable (and ?iterable) to produce
a ReflectionNamedType with name iterable, however usage of iterable in
union types will be converted to array|Traversable
