    - #### upto

          public static void upto​(Temporal from,
                                  Temporal to,
                                  Closure closure)

      Iterates from this to the `to` `Temporal`, inclusive, incrementing by one unit each iteration, calling the closure once per iteration. The closure may accept a single `Temporal` argument.

      The particular unit incremented by depends on the specific sub-type of `Temporal`. Most sub-types use a unit of `ChronoUnit.SECONDS` except for

      - `ChronoLocalDate` and its sub-types use `ChronoUnit.DAYS`.
      - `YearMonth` uses `ChronoUnit.MONTHS`.
      - `Year` uses `ChronoUnit.YEARS`.
      Parameters:
        `from` - the starting Temporal
        `to` - the ending Temporal
        `closure` - the zero or one-argument closure to call
      Throws:
        `GroovyRuntimeException` - if this value is later than `to`
        `GroovyRuntimeException` - if `to` is a different type than this
      Since:
        2.5.0

    - #### upto

          public static void upto​(Temporal from,
                                  Temporal to,
                                  TemporalUnit unit,
                                  Closure closure)

      Iterates from this to the `to` `Temporal`, inclusive, incrementing by one `unit` each iteration, calling the closure once per iteration. The closure may accept a single `Temporal` argument.

      If the unit is too large to iterate to the second Temporal exactly, such as iterating from two LocalDateTimes that are seconds apart using `ChronoUnit.DAYS` as the unit, the iteration will cease as soon as the current value of the iteration is later than the second Temporal argument. The closure will not be called with any value later than the `to` value.

      Parameters:
        `from` - the starting Temporal
        `to` - the ending Temporal
        `unit` - the TemporalUnit to increment by
        `closure` - the zero or one-argument closure to call
      Throws:
        `GroovyRuntimeException` - if this value is later than `to`
        `GroovyRuntimeException` - if `to` is a different type than this

                                    Closure closure)

      Iterates from this to the `to` `Temporal`, inclusive, decrementing by one unit each iteration, calling the closure once per iteration. The closure may accept a single `Temporal` argument.

      The particular unit decremented by depends on the specific sub-type of `Temporal`. Most sub-types use a unit of `ChronoUnit.SECONDS` except for

      - `ChronoLocalDate` and its sub-types use `ChronoUnit.DAYS`.
      - `YearMonth` uses `ChronoUnit.MONTHS`.
      - `Year` uses `ChronoUnit.YEARS`.
      Parameters:
        `from` - the starting Temporal
        `to` - the ending Temporal
        `closure` - the zero or one-argument closure to call
      Throws:
        `GroovyRuntimeException` - if this value is earlier than `to`
        `GroovyRuntimeException` - if `to` is a different type than this

The closure will not be called with any value earlier than the `to` value.

      Parameters:
        `from` - the starting Temporal
        `to` - the ending Temporal
        `unit` - the TemporalUnit to increment by
        `closure` - the zero or one-argument closure to call
