I'm working on a chess engine side-project, and I'm starting to
get into profiling and optimization.
One of the optimizations I've made involves some inline assembly,
and I ran across some apparently bizarre behavior today, and I
just wanted to double-check that I'm not doing something wrong.

So the author was plain wrong about using enums instead of
strings. The misconception is due to assuming we can use
`string` variables at compile time but we cannot (as they are
run-time data).
Not exactly either.
