signCtx(signature, priv, message, context) } func signCtx(signature []byte, priv *PrivateKey, message []byte, context string) ([]byte, error) { fipsSelfTest() // FIPS 186-5 specifies Ed25519 and Ed25519ph (with context), but not Ed25519ctx. fips140.RecordNonApproved() // Note that per RFC 8032, Section 5.1, the context SHOULD NOT be empty. if l := len(context); l > 255 { return nil, errors.New("ed25519: bad Ed25519ctx context length: " + strconv.Itoa(l)) } return signWithDom(signature, priv, message,...

This means that now, if you set a value in a context variable before `yield`, the value would still be available after `yield` (as you would intuitively expect). And it also means that you can reset the context variable with a token afterwards.

For example, this works correctly now:

signCtx(signature, priv, message, context) } func signCtx(signature []byte, priv *PrivateKey, message []byte, context string) ([]byte, error) { fipsSelfTest() // FIPS 186-5 specifies Ed25519 and Ed25519ph (with context), but not Ed25519ctx. fips140.RecordNonApproved() // Note that per RFC 8032, Section 5.1, the context SHOULD NOT be empty. if l := len(context); l > 255 { return nil, errors.New("ed25519: bad Ed25519ctx context length: " + strconv.Itoa(l)) } return signWithDom(signature, priv, message,...

    *   It is available for immediate use.
        *   See the `TF_RUN_EAGER_OP_AS_FUNCTION` environment variable in
            [eager context](https://github.com/tensorflow/tensorflow/blob/master/tensorflow/python/eager/context.py).
        *   Eager performance should be similar with this feature enabled.
            *   A roughly 5us per-op overhead may be observed when running many
