Possibly, but I've decided on self-hypnosis as the cure. I'll get

You're correct, of course. And in the end, with the admission of
parenthetic infidelity, I reveal the fact that I was never taught
C or computer science by a qualified professional.

I must have, because the reaction to my comments were fairly strongly
worded.

The "standard definition" doesn't seem to be the obvious one to
colloquial English speakers, but then we normally expect less rigor in
casual conversation.

The addendum in its original form is probably only of interest to
language historians. I don't know if I'd like to pay for a PDF
version, but a smartly bound printed copy would be a nice thing to
have.
