Would it be possible to omit the names of unreferenced nested metadata? (if you have a bunch of member functions in a class, but don't need to refer to them elsewhere (eg: those member functions aren't defined in this translation unit)) - that'd help readability/writeability, but probably wouldn't impact FileCheck. Certainly possible, but is it generally desirable? I would imagine so - is there any reason the names/numbers would be preferable? I don't know :). @Adrian?

There are certainly precedents in LLVM assembly language for specifying child nodes inline. For instance, you can write call @llvm.dbg.value(i32 %var, metadata !{}, metadata !{i32 ..., ...}) I think that would be reasonable.

I guess we'll sort that out when I get there. Sure enough.
