	I use paren's all the time.  The first C compiler I ever used
had *no* orders of operations.  It did things left to right.  Period.

So... I got into the habit of putting parens around everthing.  This was
then aggrivated when the language we used at work had a *different* order
of operation than the C compiler I used at home.

So, I will put parens around everthing so I am sure how it will be
evaluated and for clarity.


ie.
    if ( (a == 10) && (ful == FALSE) )

    return ( (bar*10) +1);

 etc.
