If you are planning on recursive inclusion, then you might want to add 
some kind of a unique number to the output variable to avoid collision:

class ERB
  @output_num = 0
  class << self
    attr_accessor :output_num
  end
end

def import path
  n = ERB.output_num += 1
  ERB.new(File.read(path), nil, nil, '_x_'+n.to_s).result()
end

One thing to also be careful with is that when a syntax error occurs, 
the file name is not printed in the exception message.  It might be 
useful to rescue the syntax error exception and include the file name in 
the exception stack.
