Yes, we need that subset. We could call that RC++ (or rC++, like RPython is a reduced Python). What I would put in that subset: - constructors/destructors

Yes, we need that subset. We could call that RC++ (or rC++, like RPython is a reduced Python). What I would put in that subset: - constructors/destructors (RAII) - auto (type inference) - class with template arguments (no nesting) - variadic templates for function parameters What I would remove: - virtual - rtti - complex templates (nesting) - no STL (or something new and/or based on POSIX) - no private/protected in classes (public by default) - or remove class (only structures) - operator overloading - namespaces - name mangling (a.b gives a_b) I imagine a good subset as something that Thorvalds could approve and ideally allow in the kernel.
