@Rushyo, what if the documentation is not enough or is incomplete? What if you really need to know all about calling conventions, because, say, you're developing a compiler (no matter the language)? Even by your reasoning, this might be something for Raymond.
Even by Raymond's reasoning, according to the linked post blogs.msdn.com/.../10190102.aspx , this is something the compiler can answer you in concrete examples, but it might take you more time to find out all about calling conventions this way than to get a detailed answer or request proper documentation.
BTW, how do you know what is and is not for Raymond? blogs.msdn.com/.../10392028.aspx . Anyway, it's not like the answer would (need to) be "In the beginning, there was a big bang, then ... calling conventions ... meaning of life ..." In the end, I'm sure people become much happier about their spent money on support and/or maintenance from a company that answers even these kind of questions.
