What is the problem this feature would solve?

Background

typescript-eslint has a rule called no-floating-promises which requires all promises to be handled (either via return or await) or explicitly ignored (via void).

It would be nice to be able to get a lint warning when leaving an Effect hanging.

What is the feature you are proposing to solve the problem?

A new rule to detect floating Effects could warn on the following circumstances:

❌ Incorrect

Effect.gen(function* () {
  Console.log('foo');
//^ floating Effect
});

const program = pipe(
  Effect.succeed('foo'),
  Effect.tap(v => {
    Console.log(v);
//  ^ floating Effect
  }),
);

✅ Correct

Effect.gen(function* () {
  yield* Console.log('foo');
});

const program = pipe(
  Effect.succeed('foo'),
  Effect.tap(Console.log),
);

What alternatives have you considered?
