How to best change the default value of dasherize (using Edge Rails, and knowing about :dasherize => false)?

Hi all,

I'm trying to turn off dasherize in all cases, since converting
underscores to hyphens breaks the way that I want to handle XML (with
E4X in Flex 2).

I've read the other threads about dasherize on this list. I'm on Edge
Rails, so I can successfully turn off dasherize for a single usage
with something like

render :xml => @task.to_xml(:dasherize => false)

I don't want to have to do this in every case, of course. So, I can
go ahead and add the following to my application.rb:

module ActiveRecord #:nodoc:
  module XmlSerialization
    #We change the default for :dasherize, since it is never what we want.
    def to_xml(options = {:dasherize => false})
      XmlSerializer.new(self, options).to_s
    end
  end
...etc...
end

This works fine.

However, I also have to change the behaviour for two of the other
to_xml methods:

to_xml (ActiveSupport::CoreExtensions::hash::Conversions)
to_xml (ActiveSupport::CoreExtensions::Array::Conversions)

(The to_xml in ActiveRecord::Errors doesn't use it.)

Anyway, the source in the Hash::Conversions and Array::Conversions is
larger, so I don't want to override the method just to change the
default. Is there any way that I can set the default of :dasherize to
false without doing that?

[I asked about this when I was on Rails 1.1 and the response was to
just add to_xml_nodash methods or modify the to_xml ones, which worked
but was unfortunate since by overriding the methods I'd clobber any
changes to them. I'm just wondering if anyone who is a Ruby / Rails
guru can think of a better way to do this now that there is actually
the :dasherize option to play with...]

I wish there was some constant I could just set to make dasherize
default to false in all three methods that use it. I'm sure I'm not
the only one...

Thanks,
