I was thinking of something along the lines of what has been proposed
here earlier:
@attr(identifier = expression)
as a storage class, like:
@attr(foo = bar + 1) int x;
and then:
__traits(hasAttribute, x, foo)
would return true, and:
__traits(getAttribute, x, foo)
would return the expression (bar+1). The expression would be
compile-time only, evaluated at the point of declaration.
You also need means to enumerate attributes.
