[Voted into WP at March, 2010 meeting.]
The current wording for the carries_dependency attribute does not limit it to value-returning functions (when applied to the declarator-id, indicating that the return value is affected), nor does it prohibit use in the declaration of a typedef or function pointer. Arguably these meaningless declarations should be prohibited.
Proposed resolution (October, 2009):
Change 9.12.4 [dcl.attr.depend] paragraph 1 as follows:
...The attribute applies to the declarator-id of a parameter-declaration in a function declaration or lambda, in which case it specifies that the initialization of the parameter carries a dependency to (6.9.2 [intro.multithread]) each lvalue-to-rvalue conversion (7.3.2 [conv.lval]) of that object. The attribute also applies to the declarator-id of a function declaration, in which case it specifies that the return value, if any, carries a dependency to the evaluation of the function call expression.
