For the examples given you haven't demonstrated your point, and you have ignored the main point being made. To repeat the main point being made: it is better for me to specify (in the source code) what the tool has to achieve, and let the compiler decide how to achieve it. It is worse for me to /ambiguously/ specify (in the source code) what is required, and to implicitly point to the compiler's man pages - and probably to hope the next program maintainer uses the correct compiler flags. >>>>> Programmers should use their ability to count not just for stack >>>>> levels, >>>>> it is a lot more effective than working to delegate the counting of >>>>> this and that to a tool which is a lot less intelligent than the >>>>> programmer.

That has already started happening in another response which has started to discuss menus/meals that people had last week! I beats me how that is supposed to illuminate the benefits of stating the peripheral's structure and letting a compiler sort out how best to generate code for it.
