There is precedent for compiler-recognized UDAs using camelCase 
in core.attribute.gnuAbiTag [1], as well as the various 
LDC-specific attributes [2]. So no matter what I choose here, it 
will be inconsistent with something.

If you strongly prefer the lower-case version, you can always 
rename it in your own code:

     import core.attribute: mustuse = mustUse;

     @mustuse struct MyStruct
     {
         // ...
     }
