Iterable(T)

The Iterable mixin provides convenience methods to collection classes that provide an each method that returns an Iterator over the collection.

Instance methods

chunk(reuse = false, &block : T -> U) forall U

Returns an Iterator that enumerates over the items, chunking them together based on the return value of the block.

(0..7).chunk(&.//(3)).to_a # => [{0, [0, 1, 2]}, {1, [3, 4, 5]}, {2, [6, 7]}]

See also: Iterator#chunk.
