Recovering from errors in generator syntax

Just making sure I understand this properly: in generator syntax, the only way to recover from an error is from within the

$()

$()

$()

$() (or

_()

_()

_()

_()), right?

For example:

Effect.gen(function*($) {
   const a = yield* $(
       someEffectThatMightFail(),
       Effect.orElse(() =>
           // do some Effect to recover
       )
   ),
});

Effect.gen(function*($) {
   const a = yield* $(
       someEffectThatMightFail(),
       Effect.orElse(() =>
           // do some Effect to recover
       )
   ),
});

Effect.gen(function*($) {
   const a = yield* $(
       someEffectThatMightFail(),
       Effect.orElse(() =>
           // do some Effect to recover
       )
   ),
});

Effect.gen(function*($) {
   const a = yield* $(
       someEffectThatMightFail(),
       Effect.orElse(() =>
           // do some Effect to recover
       )
   ),
});

That's the only place you can deal with errors within a generator. Is that right? Or is there some other strategy I'm overlooking?
