#fifth

Equal to self[4].
#forty_two

Equal to self[41].
#fourth

Equal to self[3].
#from

Returns the tail of the array from position.
#in_groups

Splits or iterates over the array in number of groups, padding any remaining slots with fill_with unless it is false.
#in_groups_of

Splits or iterates over the array in groups of size number, padding any remaining slots with fill_with unless it is false.
#including

#second

Equal to self[1].
#second_to_last

Equal to self[-2].
#split
