No, not a win. Do you read the entire source code for an entire project before trying to comprehend one part of it? I doubt it. Do you read an entire file before trying to comprehend a single function in that file? No. Do you even read an entire function before processing one line in that function? Unlikely. It's normal and correct to seek to understand one part of some code while ignoring other parts. That's why we have proper variable names, even inside functions - we could just use "slot0" and "slot1" and so on, since that's how they work to the interpreter. But we use good names, so that you can understand some code without having to first read the thing that created that variable.
