Google for "YAML Norway" for some real-life illustrations of this 
problem. The ISO country code for Norway is "no", which the YAML parser 
converts into "false".

Yes, that’s pretty much the final nail in the coffin. I’m starting to recognize 
that some of the initial appeal of YAML was due to DWIM that is almost certain 
to later come back to bite me. Looks like I’m stuck with sexps, json, or … 
wait, I could just roll my own parser! Wouldn’t take a second!

…

Just kidding.

Many thanks for the input.

John

If you'd still like to use yaml, I would like to quietly point out that each of 
the following is a valid boolean value in yaml:

- true
- false
- yes
- no
- y
- n
- True
- False
- TRUE
- FALSE
- on
- off
- YES
- NO

... but it's not strictly case-insensitive, as yES is parsed as a string
