FWIW this also works with String, trival but useful :-)

# extend String class

class String
  def insert (pos, txt)
    self[pos,0] = txt
    self
  end
end

# test it

x = "Hello World"
puts x
x.insert  6, "my "
puts x

# end

And the output:

irb(main):047:0>                                                          
"Hello World"
irb(main):051:0> Hello World
nil
irb(main):052:0> "Hello my World"
irb(main):053:0> Hello my World
nil
irb(main):054:0>
