If you need any prefix at all, a single underscore is enough, and 
it's also the tradition in other languages such as Python, C#... 
Whether a private member is exposed as property or in some other 
way, can be seen in the getter/setter, no need to classify it 
into the member declaration.

C++ kind or requires a letter on top such as m_ simply because 
any identifiers starting with an underscore are (mostly and 
certainly at the global scope) reserved (namespace pollution 
anyone?).

It's really up to you, we won't call the police ;)
