--- Comment #2 from Walter Bright <bugzilla at digitalmars.com> ---
Note that a plain 'alias' declaration specifically does not add modifiers,
storage classes, attributes, etc. It's not a wrapper. It just forwards the
lookup to the symbol. It should ignore any attributes, like plain alias does.

Added a clarification to the spec:
