The problem with leading underscores in non-global names is, as I have
discovered to my sorrow, that many people think they are prohibited. So
they challenge the usage, and then you have to waste time patiently leading
them through the standard wording. They don't believe you, think you are
missing something, and then you waste more time playing email ping-pong.

So I've given up and no longer use leading underscores. Period. That's much
easier than arguing with people.
