If strictly adhered to, it doesn't, and I've never claimed any
different. But coding standards are never strictly adhered to.
Particularly not in a codebase like LLVM which already has a good
handful in play for historical reasons. We can't expect reviewers to
be perfect either, and violations of a leading underscore rule have a
ridiculously high probability of producing malformed C++.

It's simply not worth the aggro when there are plenty of other
possibilities available that don't open us up for that failure mode.
