Examples: + + payments.sum { |p| p.price * p.tax_rate } + payments.sum(&:price) + + This is instead of payments.inject(0) { |sum, p| sum + p.price } + * Correct and clarify Array#to_sentence docs. #5458 [brad@madriska.com] * alias_method_chain preserves method punctuation so foo, foo?, and foo! may be chained with the same feature.
