/**
 * Wrapper to produce a StringView from any method that uses a stream to display something.
 *
 * The function is called with a stringstream which then is turned into a string later.
 *
 * Caveat: Make sure the stream passed to the method is actually used. Some methods seem to use a stream parameter for
 * legacy reasons. These methods internally use the "Log() << Verbose()" mechanism instead of the stream.
