Isn't this a really really really bad bug in the language specification?

Obviously you shouldn't be able to overwrite immutable values (unless you use
unsafe tricks).

What can be done to fix this hole in the const system?

Just disallowing appending const(T) to const(T)[] isn't really an option, is
it?
