Heu je veux pas etre méchant, mais lwc ne supporte pas la moitié de se que défini le C++ de base (cad sans STL)... :

Adding new features to the language is very easy. We can have delegates
tomorrow. C++-like templates *are* possible. It's also easy to implement
operator overloading for all the operators, pointer-to-member operators,
contracts, attributes, properties, singletons and generally everything
you see in other programming languages. Everything except the ability
to unwind the stack (which is thread-safe) is possible. The hard part is done...
