// clone makes a copy of value, and may update string values found in value
// with a cloned version of those strings. The purpose of explicitly cloning
// strings is to avoid accidentally giving a large string a long lifetime.
//
// Note that this will clone strings in structs and arrays found in value,
// and will clone value if it itself is a string. It will not, however, clone
// strings if value is of interface or slice type (that is, found via an
// indirection).
