Method: Sequence#slice

Defined in:
lib/sequence.rb

#slice(*args) ⇒ Object

Provides random access for the sequence like what is in Array/String. index can be nil (start at the current location) or a numeric (for #pos=) or a range. len can be nil (get a single element) or the number of elements to #read (positive or negative). The sequence’s position is left alone.
