💻 Code

let a

a = "foo" as "foo" | "bar"

let b

b = getB()

checkB(b)

function checkB(toCheck: "foo" | "bar") {
}

function getB(): "foo" | "bar" {
    return "foo"
}

🙁 Actual behavior

After running infer from usages quickfix, you get string type in a and b positions

🙂 Expected behavior

Should get inffered type "foo"

I think in case of as and satisfies clauses the type should be just copied literally?

As you can see from example this is common case for string enums, like when some function expects some string enum instead of just string, but this information gets lost

Reproduce el comportamiento en el TypeScript Playground enlazado usando el código proporcionado y, a continuación, rastrea el quickfix “infer from usages” y su manejo de assertions o satisfies clauses. Se considera terminado cuando los tipos inferidos para a y b conservan el literal "foo" en lugar de ampliarlo a string, con cobertura para el caso mostrado.
