Wow, I was taking a cut at this myself this weekend and I used the *same* names for the same functions!

I took a different approach with this one. The caller that was using this with a Vector could use a StringBuilder instead, I think. Something we can mess with later.

I think we could just do a forward declaration instead of including the entire header.

In my patch I had changed the first argument type to const LChar*.

This can just be append(name) instead since that's what the "const char*" version does. I suspect it could also use flexibleAppend to do all four appends on one line.

Ditto.

I noticed some other differences between the string adapter behavior and overloads of String::append; the big one was append(UChar32) which from an overloading point of view is the same as append(int). So I decided that needs to be renamed, at least temporarily, to appendCharacter.

StringBuilder::append, I mean

Yeah, this might have been better. I was worried since it was a debugging thing that there might be some lldb scripts that depend on it returning a Vector, but I could have just converted to a Vector at the end.

No, it needed the #include due to inlining.

I will do this in a follow up, but change all the flush() implementations at once. I didn't want to change just this one.

Done.

Oh, good catch. I'll make that change. I am curious where in the code we are using UChar32, I guess I will find out soon.
