Use when the stopping condition needs an Effect or service and predicate failure should fail the stream.

position.
When to use
Use when a function parameter must match an inferred type without becoming
an inference source.
Details
The parameter using NoInfer must still match the inferred type.
Example (Controlling inference)

// T is inferred as "a" | "b" from the first argument only
const result = withDefault<"a" | "b">("a", "b")

Effect, adapted for multiple values.
