I said it was bad because I found it difficult to read and it was
"weird". I also mentioned that it's conceivable that it has security
flaws, but that's not as big a deal. I believe I also said that it was
bad because it resulted in """arbitrary""" limitations in
functionality. So, yes, I did say why it's bad, and it's not just
because other people say so. My reasons are weak, but that's a
different story.

I also mentioned the alternative implementation, which uses a dict.
There was even already a patch submitted to make namedtuple work this
way, so I don't think I had to be too specific. R. Hettinger rejected
this patch, which was what I was referring to when I was referring to
handwaviness.

So, no.

Woo condescension.
