Equivalent of typedef in C#
...st<Customer>;
but that will only impact that source file. In C and C++, my experience is that typedef is usually used within .h files which are included widely - so a single typedef can be used over a whole project. That ability does not exist in C#, because there's no #include functionality...
How much is too much with C++11 auto keyword?
I've been using the new auto keyword available in the C++11 standard for complicated templated types which is what I believe it was designed for. But I'm also using it for things like:

Why does the C preprocessor interpret the word “linux” as the constant “1”?
...hout -x as it doesn't have an extension, so gcc doesn't know if it is C or C++. You can use gcc -E -dM -x c /dev/null or gcc -E -dm -x c++ /dev/null to get the list without having to create an empty file.

Is std::vector so much slower than plain arrays?
...ector. So much for the compiler being smart enough to optimize out all the C++ness and make STL containers as fast as raw arrays.
The bottom line is that the compiler is unable to optimize away the no-op default constructor calls when using std::vector. If you use plain new[] it optimizes them away...
What should go into an .h file?
...PL. #2 would be possible if export was supported and may be possible using c++0x and extern templates. IMO, header files in c++ lose much of their usefulness.
