Say we want different flavors of effect wrappings:

• Cats, over F[_]
• Cats, over IO
• ZIO
• Monix

We introduce an enum for these:

sealed trait EffectWrappingFlavor

pub fn Id(comptime A: type) type { return A; }
pub fn identity(comptime A: type, a: A) A { return a; }
pub fn map(comptime A: type, comptime B: type, a: A, f: fn (_: A) B) B {
  return f(a);
}
pub const MonadId = Monad(Id, identity, map);
