Long story short: in my attribute proc-macro I need to detect presence of other proc-macro attributes. It looks like I can see other attributes if they are placed after (below of) my macro and can't see ones before (above) it.
The question is: is this order specified and can I rely on it? Is there any plans to change this behavior?
I'm asking here and not on users.forum because I think this question is should be adressed directly to compiler hackers, so here I am.
