Yes, that's a nice approach. However, this approach requires you to list all your keys in advance (in the enum).

The `semi::static_map` does not require this.This is especially useful if you are writing library code: imagine you are programming a `getFont` method - you don't know with which constexpr keys your method will be called, so there is no way for you to list all these keys in an enum.

If you don't like pointlessly repeating occurrences of identifiers, you should hardly be favoring C++.

   class foo {
   public:
     foo();
     ~foo();
   };
 
   foo::foo() { }

   foo::~foo() { }

Ad nauseum.

Oh, but C++ can eliminate redundancy in this one cool case I'm thinking of!
