(Range) sub infix:<cmp> §

multi sub infix:<cmp>(Range:D \a, Range:D \b --> Order:D)
multi sub infix:<cmp>(Num(Real) \a, Range:D \b --> Order:D)
multi sub infix:<cmp>(Range:D \a, Num(Real) \b --> Order:D)
multi sub infix:<cmp>(Positional \a, Range:D \b --> Order:D)
multi sub infix:<cmp>(Range:D \a, Positional \b --> Order:D)

Compares two Range objects. A Real operand will be considered as both the starting point and the ending point of a Range to be compared with the other operand. A Positional operand will be compared with the list returned by the .list method applied to the other operand. See List infix:<cmp>
