in thread 'or' vs '', '&&' vs 'and'

Just remember that sometimes "excessive" parentheses can enhance the readability of your code. Especially when you have to "enhance" your own code 6 months (or more!) after you originally wrote it :-)

That said, for these situations I always use 'and' and 'or'.
