 * Alternatively, eliminate "topmost" and turn that into an arraylist
 of linked scopes (peers), but this will complicate plenty of other
 pieces of code.

+These are some further ideas on how to fix this bug.
+
+The routine to fix is AddLocal in anonymous.cs, but this routine and
+its side effects are complicated because it tries to maintain the
+hierarchy of ScopeInfos updates as calls are made to AddLocal (this
+happens in a few places elsewhere as well).
+
+It might be better to just record all the ScopeInfos as they are
+required and once all the ScopeInfos/blocks are tracked, then we can
+link the ScopeInfos.
+
+At the top of the CaptureContext we will have a list of ScopeInfos
+(the toplevel scopeinfos, those which dont have a nesting relationship
+between them).
+
+Without this change, fixing the bug becomes harder as we need to link
+all the toplevel ScopeInfos to the CaptureContext parent (for nested
+anonymous methods).
