No big surprise here. He's saying that Go generics are fast for simple
types (where they are essentially implemented as macros) but not
necessarily faster than interfaces when used with interfaces. The
alternative would be to have the compiler duplicate generic functions at
all types, as in C++, which has its own issues.
That's exactly as it was in Common Lisp: you'd write generic code as the
initial implementation, then do some profiling and manually specialise
your inner loops. That's something I can live with.
