Even in my company we are advised to use SBRM (Scope based/bound resource management, as explained in original post example). Lifetime of the variables/object created inside the scope will be cleared once it goes out of scope.

It does make code look ugly though.

I like it.

Many people forget that peripheral equipment need to be carefully activated and put away.

If not, you can get some very unwanted effects or even life threatening consequences.

Pre-empting the question: but how much overhead?

none.

The "nop" calls are there to "do something" so that the optimiser doesn't completely remove this example code.

Not yet sure about this feature but what about malloc() and free() at latter point of time? Is it not that effective anymore against memory leaks?
