In most cases I'd agree with you, but in some domains, such as image processing algorithms (particularly for 3d images), those kinds of loops are somewhat common, performance is a first priority, and imo are sometimes more readable with all the conditions in one place even if overall the code is still very difficult. The `return handleErr(val);` is a nicer way to do it in some cases. I'll keep that in mind though you may have to pass a lot of references to the function for it to work.
