--------------------------------------
+=== Enhanced Ranges
+
+Groovy has always supported inclusive, e.g. `3..5`, and exclusive (or open on the right), e.g. `4..<10`, ranges.
+From Groovy 4, ranges can be closed, open on the left, e.g. `3<..5`, right or both sides, e.g. `0<..<3`.
+The range will exclude the left or right-most values for such ranges.
