Hi Valentin,

If you want to check a "non-trivial" plugin, you can always try out the C++ one we've written for the MEM: https://github.com/MoMEMta/MoMEMta-MaGMEE. You won't be able to compile the resulting code without installing our framework, but the plugin output works nonetheless.

Regarding the 'using namespace' statements in C++, it's a problem if they are used in header files: any code directly or indirectly including those headers will get polluted by the namespace, which can cause collisions. Those statements should always only be included in non-header files.

Cheers,
Sébastien
