I have my own class (which I don’t want to modify anyhow):

class Foo
  def each
    # iterate over some database
    yield item
  end
end

Now, I would like to turn it into an array. I’m doing this:

f = Foo.new
array = []
f.each do |i|
  array << i
end

Is it possible to do this in one line? Something like:

array = to_array(f)

Is there a function in Ruby like to_array? I know, I can write it myself, but maybe it already exists? I need it in every project.
