class SyntaxTree::RangeNode

RangeNode represents using the .. or the … operator between two expressions. Usually this is to create a range object.

Sometimes this operator is used to create a flip-flop.

if value == 5 .. value == 10
end

One of the sides of the expression may be nil, but not both.

right[R]
