Hmm.  Since you'll probably be flamed out of existence for this, I
won't bother.  (In case you haven't yet figured it out, '==' is not
guaranteed anywhere to evaluate left-to-right.  Your second example
[deleted] doesn't use '==', and is correct.)

I just have a suggestion to make to Steve Summit:  do you think this
is a good question to put in the FAQ?  I vote to put it in.

Thanks,
