I could live with "extract<T>(source)", but I wonder if it would be more 
precise to use something like "variant_cast<T>(source)"? My only concern with 
the name "variant_cast" is that if (when?) we do get a bounded variant class, 
it will probably be named "variant", so we run the risk of confusion: it will 
be clear that "variant_cast" works with "variant", but why does it work with 
"function" and "any"?
