Which is why I don't understand the resistance against introducing
such a beast.

Whether it is a ternary operator or something more general, the
proposed construction are usually more readable than the
python construction with the same functionality. 


The decorator syntax IMO provided much less improvement in
readability for functionality that was already provided
and that got implemented.


A ternary operator (or suitable generalisation) would IMO
provide a greater improvement what readability is concerned
but is resisted all the way.
