You may go very far unharmed, but it will get you sooner or later, and the later it gets, the harder to discover. Such things are pretty hard to track, because compiler won't help you, and if it complains, it will probably give you a wrong error code. Sometimes I think that the Hungarian prefixed notation was introduced to distinguish prefixed user objects from unprefixed keywords :)
