> Beginning with the type inference (ie using "auto" to declare vars). GCC (and possibly other compilers) had typeof in the '90s well before D was first released. Macros in the form: #define TYPEOF(name, expr) typeof(expr) name = expr Were widely in use since then. I'm sure that C++ borrowed concepts from D, but type deduction (not inference BTW) is not one of them.
