I think my compiler understands C++11, but maybe not. Instead of trying it on existing messes of source code which are buggy anyway, is there some simple "hello world" level snippet of source code I can try to compile, which if it does compile without error, proves the compiler is reading it as C++11?

2Try passing `-v -std=c++11` flags to your compiler. – Basile Starynkevitch Jan 16 '15 at 18:44

1You can use the standard "hello world" program, just replace the string with a raw string literal - `R"(Hello World!)"` – Praetorian Jan 16 '15 at 19:42

@Praetorian R could be a macro. – Neil Kirk Jan 16 '15 at 19:58

Try this one,
auto f = [](){};
or write some code with rvalue reference.

I'm not entirely sure this is correct, but from what I'm reading in 2019, it looks like that in the upcoming C++20, []<>(){} will be legal. – DarenW Jul 16 '19 at 05:02

Shortest thing possible:
[]{};
Is's a lambda-expression without argument list.

The Problem is that compiler usually don't support a new standard completely from the start. Meaning, they may support one c++11 feature, but not another.
However, as far as c++11 is concerned, I think VC++ is the only major compiler that doesn't fully support it, even though you may have to enable the c++11 mode manually. For g++ you e.g. have to supply the compiler flag -std=c++11 (or -std=gnu++11) - the same holds true for newer versions like c++14).
