Pardon me, no flames intended to the poster, but I just HAD to bring up
a point with such a good example available. I know that somebody somewhere,
with nothing better to do, decided what the "correct" method of punctuating
near (") quotation marks would be. The poster has "correctly" followed the
"rules", and I am not finding any fault with the poster.
My point is this: why put (,) commas and (.) periods, or any other
punctuation for that matter, within a technical quotation?
for example:
> perfectly legal to overload the logical operators "and,"
> "or," and "xor."
Am I to assume that the poster is referring to (and,), (or,) and (xor.) ?

Likewise, are we looking at (/=.) and (/=,) ?
Context and careful re-reading help the reader to understand what is really
being communicated, but is it REALLY necessary?
I admit, in this particular case, the above assumptions are rediculous.
There are, however, many topics that could be discussed, including a few
languages, where these assumptions would be quite reasonable.
Again, there are absolutely NO FLAMES INTENDED toward the poster, just
FLAMES for the rules.
Thanks for listening.
I feel better now.
