C++ish I'd accept (but see the list of languages I've worked with on my home node).

Perhaps I was being too specific when I said "our tells you something is "global" where you declare the variable". I was more intending to suggest that using an identifier over a wide scope puts more onus on the identifier to convey meaning and that any amount of "documentation" at the point of declaration doesn't help at the point of use. A simple g prefix is a heads up that this variable has large scope: beware, here be dragons. Most of the time the extra markup to convey that the variable hails from some package or another is unnecessarly heavy handed and doesn't add much value anyway.
