I plan to add a Nullable struct to Phobos (akin to C#'s Nullable,
Boost's Optional).
Apparently a good design is to define Optional!T with a minimum of
member functions (ideally none) and have it use the "alias this"
feature to masquerade as a T. That way Optional!T looks and feels much
like a T, except that it supports a function
bool isNull(T)(Optional!T value);
Am I on the right track? If so, what is the name you'd prefer for this
artifact?

How about: Maybe!T
Got that from Haskell :-)
I also feel the bikeshed should be colored 'Maybe'.
