Chris, I was not arguing that at all. I was saying some rationales about how to order choices exist based on ideas like efficiency or other considerations. Sometimes people are mistaken as something may take constant time as implemented. And yes, many rules have countless exceptions. For example, if something is expected to rarely or never happen, code within that branch may not be needed to be optimized in any way as long as it works in the remote chance it is called.
I think what was suggested here is more about code readability considerations and for some of us, making us stand on our heads to puzzle things out is harder than ordering longer items ...
