Fully agree with you. The problem is many people don't know how to read code properly: they try to read all the details at once, instead of surfing at the top

Fully agree with you. The problem is many people don't know how to read code properly: they try to read all the details at once, instead of surfing at the top level(s) and going deeper only when they actually need. Such people are the bad developers who write bad code bacause they cannot read. My personal mantra with copy&past while programming is: if your mouse gave you a little electric shock on pasting, would you paste it anyway?
