Kenji Hara:
I think adding new keyword/attribute just for readability is overkill.
Making the code more explicit and easy to understand, using the right words, is rather important. So I like @unique, that can probably be re-uses for another purpose.
What's worse than having many keywords is having them with multiple meanings. Otherwise are you willing to explain again and again to future people in D.learn that specific "const" doesn't really mean const, it really means... and so on :-)
