Most people use the term "Hungarian Notation" to mean only adding an indicator of type to a variable or function name. While this is one of the ways in which it has been used (and actually made sense in certain old environments, although those days are long, long behind us now), it's not the only way that it can be used.

We can use the same concept (prepending or appending an indicator from a standard selection) to denote other, more useful categories that the environment won't keep straight for us, or won't warn us about in easy-to-understand ways. In my own projects I usually append a single letter to the ends of my variable names to indicate scope, which helps me stay more modular, and also allows me to choose sensible variable names without fear of clashing with something else I've forgotten about.
