Subject: str1 = str2 is not a copy?!?

I have:

File.foreach(data_file) do |line|
  line.strip!

  puts line

  base_name = line

  puts line

  base_name.sub!('www.', '')
  base_name.sub!(/\.\w+$/, '')

  puts line
end

Which outputs:

www.domain.com
www.domain.com
domain

WHY is var line getting changed by operations on var base_name? Isn't 
'base_name = line' supposed to create a copy? '=' in this case seems to 
be acting like an alias or something.

BTW, is there a foreach function that automatically strips off the 
newlines from line? Returning the record separators is silly.

Currently hating Ruby,
Joe
