Yeah gdb is evaluating the value of the attribute then assumes it's a reference, which seems natural. It's not being picky about forms. Using form (or actually, class) to distinguish different meanings of an attribute is something that happens in DWARF, but the difference in meaning isn't specified for this case (yet). The committee might or might not bless this, might prefer to use a different attribute for specifying a parameter index. You'd have to send in a proposal and see what happens.
