## Quick comments
- Dag Sverre Seljebotn: C++ has a huge problem with people abusing metaprogramming ("generics") to do compile-time metaprogramming. I really wished Go had gone down the path of Julia, which offers hygienic macros. Even if it is kept strictly at a compile-time barrier and no run-time code generation, this would at least avoid all the bad tendencies we see in the C++ world that comes from their templating system. Things you can do with generics you can usually pull off with macros too (e.g., `IntMap = MakeMapMacro!(int,int)` or similar, then use IntMap as a type).
