Could be profiled though?

Sorry, something went wrong.

Maybe automatic branch probability is enough here?
If not just specifying the probability might be better and more practical, in practice it's very likely to happen that the field is not set, right?

You mean branch probability in the CPU? I was more interested in removing the code in the PE.

Yes. It's just an Invoke, and it would only fold interestingly if the Rope is constant, right?

For LeafRope, which all String literals are, the field will be non-null. For ConcatRope and SubstringRope, it'll be null on first access. I was trying to not penalize the cases where we have the bytes already.
