Description
There seems to be no way to have an owned version of Arguments<'a> in third-party libraries because there is no way to access the members of Arguments<'a>.
One important usage of this is to build an async logger. Without this the logger has to do the formatting in the caller thread, which more or less defeats the purpose of the async logger.

Start by investigating core::fmt::Arguments and the ownership and thread-safety constraints described in the issue. Compare those constraints with the async logger use case; done should be a documented design for an owned representation that can be sent over threads.
