SumType is a generic discriminated union type for modern D. It is 
designed to
be an improved alternative to `std.variant.Algebraic`.

   - Pattern matching, including:
     - Match-by-introspection ("if it compiles, it matches") (★)
     - Multiple dispatch (★)
   - Support for self-referential types (`This`).
   - Works with `pure`, `@safe`, `@nogc`, `nothrow`, and 
`immutable` (★)
   - Compatible with `-betterC` and `-dip1000` (★)
   - Zero runtime overhead compared to hand-written C
       - No heap allocation
       - Does not rely on runtime type information (`TypeInfo`) (★)

Starred features (★) are those that are missing from `Algebraic`.

With this release, SumType's public API is officially considered 
stable. No
breaking API changes will be made from this release forward 
without a major
version bump.

Improvements since 0.10.0, the last announced version:
   - Copy constructors of SumType members are now called correctly.
   - Self-referential SumTypes can now contain self-referential 
Algebraics, and
     vice versa.
   - SumType is now tested on Windows in addition to Linux and Mac
