Code inspection: Redundant 'else' keyword

Certain if-else conditions can have their else clause removed without changing the semantic. Consider the following method:

public int Sign(double d) { if (d > 0.0) return 1; else return -1; }

In the above, the else statement can be safely removed because its if clause returns from the method. Thus, even without the else, there’s no way you’ll be able to proceed past the if clause body.
