Rails - Apr 2012 - trying to work out what is going on with monkey patch of String

Somewhere in all of the ruby code that gets included into this app I
am working on, there is something that defined String so that the
following is a valid statement

puts "contact us at " +
"info-GXcTff7tL0M@public.gmane.org"[] + " and say hello"


 The app that runs, is able to include that stuff and Ruby doesn''t
complain. When I try to write a test module and
include some of the code, ruby complains beuse my load paths or some
part of the configuration is different. I am not really sure.

 If I monkey patch string like below, it seems to stop the errors, but
I am not sure if it could be causing other problems.

class String
  def [](x=nil,b=nil)
    self
  end
end

I am on windows, but I am using cygwin. I did something like what''s
below, but did not find where [] might be defined:

 find . -name "*.rb" -exec grep -A 15 "class String" {} \;
-print > /
cygdrive/c/tmp/str-patch.txt


Any other ideas to figure this out ? How can I tell inside irb or
something what the code is for "info-GXcTff7tL0M@public.gmane.org"[]
or where it is defined ?

You could use ruby-debug (assuming that is available on Windows, I
don''t know) and step into "string"[]  to see where it is
defined.
