Description

Quite a bit of work was done for the tree visiting support in the trunk branch, but the 1.2 branch lacks these changes. For the most part, these changes can be directly back ported from Trinidad 2 to 1.2 leveraging the APIs that Blake created for 1.2 tree visiting (like the VisitResult and VisitContext as examples).

Without these changes, there are bugs that may be found in 1.2 if users begin to leverage tree visitation.
