As with many error messages, the message is very much correct, but some
folks may find in confusing. Given that error messages tend to be written
from the standpoint of what the compiler sees rather than from what the
programmer meant, it can be a bit difficult to write good error messages
that really help a confused developer figure out what's wrong with their
code. But creating enhancement requests in bugzilla whenever you find an
error message confusing can lead to improved error messages. Without that,
it's unlikely that such messages will ever be improved.
