Julian Hyde commented on CALCITE-4224:
--------------------------------------
Looks good. I might add 'This method is intended mainly for use while debugging
code in an IDE, as a convenient short-hand for RelOptUtil.toString. We
recommend that sub-classes do not override this method'.
Your point about 'final' not combining with 'default' makes sense.
Does anyone has an idea for a better name than 'tree'?
