It may be true that you are not using different languages, but without a
compelling argument for one form over another, one should generally take
the most general form that is understood and practiced by the majority.
You have not made a compelling argument for subverting usual semantics
to contort the logic into your vision.

Your opinion is one thing... and this is indeed opinion, but you
entangled it with prescription:

    In my opinion, whenever your choices exceed two, use switch.

You are certainly permitted your opinion, as I am too. I am offering my
opinion that your advice is bunk... and I have followed it up with
argument to back my stated views.

This is certainly true, when you program for yourself, and you will be
the only maintainer of that code. But down the road it is quite likely
someone else will view that code and think to themself... WTF! And that
makes it a poor judgement call. Anyone can write Perl, but how many can
write Perl that a newbie can understand?

I'm not looking for gratification... merely hoping to ensure that
readers of your niche style understand that it is niche, and that it is
not really the best option of all available options. You are welcome to
disagree, your opinion is your own, but as you have argued, we are all
entitled to our opinion. Those opinions with the greatest merit should
have the better supporting arguments (one would hope anyways :)
