I meant it to be ugly. The idea was to incentivize use of thread local storage 
to avoid hidden race conditions.

`__traits` was also meant to be ugly. The idea was these things are meant to be 
under-the-hood machinery that should be wrapped up in a nice library function 
implementation, and regular users shouldn't be seeing it.
