I've implemented the ability to disable default initialization. This
makes it practical to implement a library based "NotNull" type without
a special syntax for it. The rationale for this is (rather than making
it builtin) one can now build any type that is a restricted subset of
another type. I suspect that a non-null type is just scratching the
surface of this ability.
Awesome!
How does it deal with arrays whose elements have no default constructor?
I believe increasing the length of such an array should be an error
(which likely also excludes decreasing it except for slices).
Testing concludes that changing the length of the array indeed appends
structs to it, with no compile-time error. Should I file this in BugZilla?
