You get dangerously into the "wart" territory from C++.

Another example - in ruby. I really like the Pathname library and use it a lot. Even in my OWN programs, where I almost ALWAYS immediately turn a path into a Pathname, I still find myself calling Pathname functions and getting errors because the type is a string. I've found myself naming parameters - lets say it's a data file - "data_pn" to reassure myself that i should indeed pass in a pathname and not a string.

This is just re-engaging the hungarian notation "warts" pattern in another place and time.
