Not the first letter. The entire symbol should be in
lowercase_with_underscores as opposed to StartAllWordsWithCaps.
The requirement is that members and locals should be clearly
distinguishable.

There won't be more than one style of this in a given library. Official
coding standard or not, people who work on the same piece of code do settle
on a common basic style. No need for further regulation here.

Functions and methods have () brackets after the symbol. No problem.

And for this:

>   SomeVariable some_variable SomeVariable SomeVariable SomeVariable

It's clear enough IMO.

No ;)
I know that I have to distinguish vars from functions, so I automatically
search for round brackets. Actually I didn't realize that the two examples
were different until I was done. ;)
