I have YAML documents generated in Perl and Python that I process with
Ruby.

Problem: Ruby wants to auto-interpret boolean flagged words, example:

---
words:
  - yes
  - put
  - it
  - on
  - the
  - off
  - setting

gets loaded in Ruby as

[true, "put", "it", true, "the", false, "setting"]

Basically the latest Perl and Python YAML modules I could find won't
quote some of the words that Ruby's YAML would. (Things like on, off,
yes, no, +) Perhaps they conform to a different version of the YAML
spec. I find the incompatibility a bit frustrating.  I can and have
easily hacked the other modules to do the compatible thing but there
are political admin maintenance issues surrounding my patching all the
company computers with this.

I'll not comment right now on whether I think it was a good idea to
flag these items as special to begin with.  I'd just like to know if
there's a simple module over-ride hack or module parameter setting that
I can set or clip into my scripts to deal with this problem.

Thanks.
