IMHO, first of all, it's a QA bug.

#1 and #3 are steps toward the same user visible mitigation: inform the user the functionality is missing.

The lack of expression evaluator reach is almost always considered a bug by a user, so transforming it into a proper error message simply makes it a less severe 'bug' from the user's perspective.

Given that the syntax and naming of features is different from language to language, the Expression Evaluator's must provide user visible error messages that reference those features.

Do you think the lack of support for this in ICorDebug would be considered a defect by Andreas Zeller's definitions? If not is this not a bug? Are Zeller's definitions lacking for some practical cases?

Steve - where are Zeller's definitions?

Sorry about that. They are in his book "Why program's fail". Fortunately Chapter 1 is online.

The distinction is defect, infection, failure:

I'd claim this is a failure from the user's point of view. But is there an infection or defect?

I think you could make an argument to classify it a lot of different ways. I think Zeller's definitions are hard to apply here.
I wouldn't say Incomplete features are bugs.
The closest he gets is alluding to it here: "In a modular program, a failure may happen because of incompatible interfaces of two modules."

Resolving functions and func-eval syntax

I got a question about MDbg's func-eval syntax, which brings up a nice point about function resolution:...

Invoking a virtual method non-virtually

Method calls using the C# ‘ base ’ keyword get compiled to an IL ‘ call ’ instruction, rather than the
