Looks useful.

- The author's name is spelled wrong.

- The description of `auto enum` makes it not fully clear if the 
compiler attempts to interpret the argument with CTFE or not to check 
whether it is a compile-time constant. Same question about overloads. 
(Though for overloads I would expect CTFE to be attempted, as in the 
first step it has to be determined which overloads even match.)

- The special-case qualifier and storage class behavior is not 
necessary, just make it behave like a normal `enum` variable.
