Ruby array shortcuts - "&:" and "&method"

Call a method on every items with &:

So this:

[:foo, :bar].each do |item|
  item.to_s
end

Can be reduced to:

[:foo, :bar].each(&:to_s)

But, what if you want to call a method for each item in an array, and this item should be a parameter for this method?

Call a method with every items as a parameter with &method

So this:

[:foo, :bar].each do |item|
  puts(item)
end

Can be reduced to:

[:foo, :bar].each(&method(:puts))
