Well, the code in this answer is obviously neither C nor C++, so this is fine only if we scrap the requirement. Then any answer may qualify because a hypothetical compiler might just produce the required program from any input.

How are strings passed in .NET?
...ould be Foo(char** bar) (or Foo(char*& bar) or Foo(string& bar) in C++). Sure, it's not how you should think of it everyday, but it actually helped me finally understand what is happening under the hood.

Do sealed classes really offer performance Benefits?
... they'd either need to modify C# to allow ((string)null).methodCall() like C++ does, or they'd need to statically prove that the object wasn't null (which they could do, but haven't bothered to)

What are copy elision and return value optimization?
...pyable, e.g. because they have a private or deleted copy/move constructor.
C++17: As of C++17, Copy Elision is guaranteed when an object is returned directly:
struct C {
C() {}
C(const C&) { std::cout << "A copy was made.\n"; }
};
C f() {
return C(); //Definitely performs copy elis...
Why does ReSharper tell me “implicitly captured closure”?

In a low level language (C, C++ or whatever): I have the choice in between either having a bunch of mutexes (like what pthread gives me or whatever the native system library provides) or a single one for an object.

What are the benefits of dependency injection containers?

Performance optimization strategies of last resort [closed]
...11/26:
There is now a SourceForge project containing source code in Visual C++ and a blow-by-blow description of how it was tuned. It only goes through the first half of the scenario described above, and it doesn't follow exactly the same sequence, but still gets a 2-3 order of magnitude speedup.
