You mentioned UFCS, but if it is a template in a library then
user defined UFCS shouldn't work. The only valid case I can think

__traits(compiles) is a code smell. There's usually a better way
to express it, and as is with the case you are talking about, a
different feature would be more appropriate and provide better
