Add array items to array in one line

I am building a CSV object and I have a dynamic set of header items. I build this 'header' row as follows:

headers = ["name", "email"]
questions.each do |q|
  headers << q
end
csv << headers

Although this works just fine, what I would like to do is have the call in one line without having to add the headers variable first.

So something like:

csv << ["name", "email", questions.each { |q| q }]

Obviously the above doesn't work because the each returns the 'questions' array.

Any suggestions?
