I hear you. but do what I and some others are doing. wherever you can get away with it put the $ after, as in "10$". let's be the change we wish to see in the world. I also try to express dates in sort-friendly format wherever I can, like "2015 Feb 7" (or 20150207 if computer must parse or align, etc). I also express measurements in metric/SI wherever I can. I also never bought into this whole "put TL;DR at the end" anti-pattern I see some folks doing (assume young) when I can continue to have a "summary: foo" at the beginning, which is clearly better in two particular ways.
one could argue that "10 USD" is even better overall, with the negative of requing two extra chars.
note my choice of words "wherever you can get away with it" :-)
because I do take those situations into account. if it would cause a problem with others I don't do it. in my own notes or when dealing with others whose brains I know can handle it, I do.
