public final class IntervalExpression
extends BinaryExpression
implements IIntervalExpression

Represents an interval expression in the Gosu grammar:

interval-expression
  <bitshift-expression>
  <interval-expression> .. <bitshift-expression>
  <interval-expression> |.. <bitshift-expression>
  <interval-expression> ..| <bitshift-expression>
  <interval-expression> |..| <bitshift-expression>
