+// This is different from rewind in its multi-directional
+// requirement and in that its argument is strictly an input cursor (index).
+//
+// For char streams, seeking forward must update the stream state such
+// as line number.  For seeking backwards, you will be presumably
+// backtracking using the mark/rewind mechanism that restores state and
+// so this method does not need to update state when seeking backwards.

+// Currently, this method is only used for efficient backtracking, but
+// in the future it may be used for incremental parsing.
