Week 2 status:

     - `@rvalue ref` attribute:
         - `auto @rvalue ref` for function parameters expands to 
either `ref` or `@rvalue ref`
         - `auto ref` for function parameters retains its current 
         - `auto ref` on function returns infers refness properly 
between `ref`, `@rvalue ref`, and no ref.

     - `@rvalue` or `__rvalue` as a type constructor[1]:
         - grammar definition[2]
         - enable both syntaxes `@rvalue` and `__rvalue`
         - only usable with ref or with pointers
         - ability to cast to or from `@rvalue`
         - implicit conversion to or from `@rvalue` allowed except 
with pointers
         - special behaviour with function calls where rvalue 
arguments are implicitly `@rvalue` while lvalues need an explicit 
         - `@rvalue` ref is overloadable with bare ref
         - recognized as a type specialization with `is(T == 
         - D and C++ name mangling
         - works with ctfe, inliner, optimizer, and escape analysis
