What do you mean there's no alternative to C++ for industrial use? What ever happened to the billions of lines of code in Fortran, Cobol, Java, Perl, PHP (industry uses the web just like everyone else), Python, Bourne Shell, Awk, JCL, Forth, BASIC, Visual Basic and yes, even Lisp?
When you say that "any directly-useful core-language feature that doesn't map to a machine instruction or two indicates a language design failure", do you really consider shell, make, Perl or python failed languages, which should be forgotten in favor of C++?
