I can understand using parenthesis when operator precedence isn't
working the way you want or expect, but I certainly would not recommend
using it for basic arithmetic with multiplication, division, addition
and subtraction. The rules of precedence for multiplication and division
are well known and well-understood. If a language failed to implement
them that would be a bug.  I think for the simple things extraneous
parenthesis makes expressions more difficult for a human to parse
because he will tend to second guess himself owing to extra parens.
