Well, no, as well all know. However this misapprehension comes up time and time again, and surprisingly there doesn't seem to be a single question addressing precisely this issue (though it's covered by lots of related questions).
So do we need a Danuesque canonical question and answer(s) with the title above so we can point people to it? If the consensus is yes then I hereby volunteer to create a community wiki question and a trial answer.
If I've missed an obvious Q/A that already covers this then shout and I'll delete this question.
