The Ruby convention is aMessage which is really more clear. i.e.
"message" could be of type string or of type Unicode or anything. I'm
sure I've got code on my computer where message was of any of these
types.

After all, lower case names are not ALWAYS used for instances of a type.
Sometimes they are merely descriptive of the variable's role. If you are
trying to say that an instance is an instance of a class then the aFoo
convention is very clear.
