[chuck-users] ++ return value

The advantage of using the ++ and -- operators is that you can change
the value of one variable and then further use it in an expression.
Consider this:
++i +=> x;
This command will increment i, then take the incremented value and add
to x. In many situations, the ++/-- operators lets you write compact
yet readable code. Consider these C statements:
Statement 1:
i=i+1;  x=x+i;
Statement 2:
i=i+1;  x+=i;
Statement 3:
Statement 4:
x+= ++i;

They all do the exact same thing, but at least in my experienced eyes,
I know which one reveals most clearly what is going on.
