Answer 1

array = %w[one two many]

array.each do |ele|
  a=<<-TEXT
  This is some text and
  this --> #{ele} <-- is the ele!

  TEXT

  puts a
end

结果是

This is some text and
this --> one <-- is the ele!

This is some text and
this --> two <-- is the ele!

This is some text and
this --> many <-- is the ele!
