Compiler-recognized UDAs are an established feature of D. See 
[`core.attribute`][1] for more examples.

I suppose you'll have to take that up with Walter, since he's the 
one who vetoed "nodiscard".

To be honest, though, I can see where he's coming from. When 
writing DIP 1038, I made a conscious effort to avoid using the 
term "non-`@nodiscard`", due to the double negative. With a 
positively-phrased name like `@mustUse`, that problem disappears.
