Oh come on, that is totally taken out of context.  A better analogy
would be requiring them for the addition operator.  There are times when
it's clearly useful to use parentheses for clarity.  But that hardly
means they should be _required_.

	x = a + b # illegal, should be (a + b)
	x = (a + b)*c # fine
	x = a + b*c # illegal, should be (a + b*c)
	x = f(a + b) # illegal, should be f((a + b))
