C++11 also introduced new problems, such as the strange interaction between brace-initialization and initializer-lists (though that was partially fixed several years later), and the fairly arcane rules around move semantics with minimal compiler support (for example, it would be great if the standard required compilers to emit an error if a moved-from object were accessed).

I know Lisp is minimal, I'm just saying that I expect there are Lisp fans who won't acknowledge (or would excuse) any shortcomings in the language, just as there are C++ fans who do the same for C++.
