I think, it would be important to first collect every possible style
element in the wild and document what people are using in reality.
That would be interesting. I'm not too much in favour of a style "guide"
however. Let people be creative.

I often put it last (and it's specified to be that way e.g. in

I use the underscore style sometimes but often a simple "dash" style:
"r some-thing" instead of camelCase. My reason: It doesn't need any
Shift-key-combinations on German keyboards, and I find camelCase hard
to read.

When I want to name matching send/receive pairs I use $0-some-s and

I always seperate $0 with a $0-dash. $0myGod is easy to misunderstand.

Nice idea. I never did that, though.
