Agreed. My two cents: C# has `yield return` and `yield break`. 
The funny thing is, if D were open to contextual keywords, we 
could do the same. Then, `yield` wouldn’t even have to become a 
keyword. Alternatively, use `yield_return` and `yield_break`, 
which, yes, are valid identifiers, but have a near-zero 
probability being present in existing D code.

If anything, the proper way to make `yield` into a keyword is 
`__yield`, not `@yield`.
