Oho. Followed by a capital letter? Interesting.

I always thought that "all identifiers with a leading underscore were reserved". I just consciously ignored it, and have never had a problem in years. But I was also always using member variable names like "_children", "_childCount", etc, not "_Children".

In fact, here's a reference: http://msdn.microsoft.com/en-us/library/e7f8y25b(v=vs.80).as... (It's in a "Microsoft Specific" block but says it's part of the ANSI C standard.) It applies to C, and it also applies to identifiers staring with two underscores.
