extern(C) int bar();
@bar() void foo(){}
//pragma(msg, __traits(getAttributes, foo));

void main()
{
    auto x = __traits(getAttributes, foo)[0];
}

is compilable and runnable when linker knows where bar() is.

So this is actually supposed to work? The documentation says:

User Defined Attributes (UDA) are compile time expressions that can be attached to a declaration.

I guess the documentation is wrong or at least unclear in that case.
