It's about time we added the Astronomical Unit! We'll use the slightly older "AU" symbol, rather than "au", to avoid confusion with our ubiquitous namespace.

So how much confusion would be causing if this was au (and/or the label was "au")? Given it's in the symbols namespace, it seems like it would be tractable?

Surprisingly, it... works? https://godbolt.org/z/x5qzvE5fK
Feels a little like tempting fate, but I don't know... maybe we should do it?

Here is an example, https://godbolt.org/z/K1j1rdsGz, courtesy of Arthur O'Dwyer on the C++ slack, which convinces me that we should avoid reusing the namespace name au as an instance name.
