BTW, this is a non-issue with C# 1.0 and later due to `yield return` syntax.

Sorry, I'm skeptical -- how exactly does a 'yield return' resolve the divergences between functional programming & mutable data structures?

My layman's impression was that 'yield return' was largely syntactic sugar around an iterator, rather similar to Java.

The comment you responded too were talking about debug experience.
