+ * Expression parser: Optimize another concatenation case by using iteration
+ instead of recursion.
+ We have a relatively small recursion limit of about 10 operations. This
+ is a compilation limit (a define). It can be hit if many expr vars or
+ function calls are concatenated. The new optimization is very similar to
+ the existing one, which optimizes consecutive concatenations in node2 of
+ the tree. The new one optimizes consecutive concatenations in node 1.
