If the function is only called for side-effects (I.e., it returns nothing) then don't return anything -- You'll know by looking at the end of the function that it's not supposed to return anything. Adding the gratuitous 'return' seems of dubious benefit. I rarely write a function that doesn't return anything, come to think of it... -- Some people have a "gift" link here. Know what I want?
