I was wondering about this too, but I cant think of any operator other than
conditional selection that requires short circuit evaluation.

That said, the chaining of conditional selection operations qualifies as a
higher than ternary operator.

Im still of the opinion that an operator akin to the C ternary operator,
which is available in all of the commonly used and taught languages (C, C++,
Java, C#, Javascript), is the way to go.

example:

sign = (x<0?-1 : x>0?1 : 0)

or

sign = (x<0?-1, x>0?1, 0)

or

sign = ?(x<0:-1, x>0:1, 0)
