Understanding the Role of the `_` Variable in TypeScript's `Effect.gen`
I didn't find this in the docs; but in the examples it is used:
What is the purpose of the variable? (adapter it seems to be called from the type); Whether or not I include it, Typescript suggests that the return type is the same either way.
i.e. these are equal?
```ts
const sql = yield* (makeClient);
const sql = yield* makeClient;
```
