What could be done however, is finding a coherent best subset of current available options which are defined as "the current", blessed C++. Smaller than C++ as a whole, simpler to fit in your head (hopefully), and setting the rest as deprecated. but still complete and coherent.
Maybe it's already done, in that case it just lacks a name a website and more publicity !
What I would put in that subset:
- constructors/destructors (RAII)
- auto (type inference)
- class with template arguments (no nesting)
- variadic templates for function parameters
- 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 wouldn't, but some might.)
