You should be able to read a function from top to bottom and it should show you the whole procedure at a given level of abstraction. Hiding the details is the heart of what programming is. I always try to write code like fn foo() { let foo = do_first_thing(); let bar = do_second_thing(); do_third_thing(foo, bar); } whenever possible. Then you can see the abstract overview of what the code does at a glance, but you can drill down into the details if you need to.
