The reason to use ASDF logic would be to have multiple files,
one for each implementation, and a fallback file for unsupported
implementations.

You can also wholly avoid ASDF logic, by using your own build script,
or using Bazel.
One advantage of Bazel is that it currently only supports SBCL,
so you don't have to support other implementations.

Certainly the game is rigged. Don't let that stop you;
if you don't bet, you can't win.
