My point is that "I'm confused because I haven't read the 
documentation" is a very different complaint from "I'm confused 
because this feature is inherently confusing."

`@mustUse` will be documented in both the language spec ([PR][1]) 
and the DDoc for core.attribute ([PR][2]). If you're still 
confused *after* you've read the documentation, feel free to come 
back and complain to me then.
