[dgc (Don Cruickshank)]

In http://ruby-doc.org/core-2.2.1/Array.html#class-Array-label-Creating+Arrays

The documentation for the Array.new method is missing the fact that the element index is available to a given block.

E.g.

Array.new(4) { |x| x } #=> [0, 1, 2, 3]

[cremno (cremno phobia)]

The actual Array.new documentation mentions and also provides an example for this:

http://ruby-doc.org/core-2.2.1/Array.html#method-c-new (second code block)

[stomar (Marcus Stollsteimer)]

Although it's already documented in Array.new, an additional example in the class documentation cannot hurt; so I'll add one.
