Avoid unnecessary parentheses. The grammar of q is simple and there is no precedence order for the primitives. For example, the expression to multiply a by the sum of b and c:
a*b+cshould not be written
a*(b+c)Redundant parentheses are visual red herrings.
Although extra parentheses are useful as training wheels, most q programmers eventually internalize q syntax.
On encountering a parenthesized expression one assumes the parentheses are necessary. Do not burden your reader with the task of discovering that they are not.
