C++11 possiblity to omit `sizeOfArray`

[Floessie]

Hi,

there could be a possibility to omit the sizeOfArray parameter with C++11. Here is the relevant code snippet on StackOverflow. As it's missing a const, here is another example (see "Alternative C++ 11 implementation").

This would be very useful. Apparently C++11 is the default in Arduino IDE since 1.6.6 (released 4 years ago), so I think it would be viable to do this.
