I think it is too bad a nested example wasn't required.  If the
ternary operator is added, and Python continues relentless world
domination ;-) , I will probably have to puzzle out somebody's
unfortunate nested ternary operator expression... at least once in my
life.

This might give even the most rabid supporter pause.

It is also too bad that examples of how to helpfully reject all
ternary operator forms were not given.

There would be 2 cases of rejecting the ternary operator:

1.  Horrified, but still able to rank 3 in order of least offense.
    (These would be people who have been steeled by voting in recent
    US presidential elections...)
    These voters could follow the format of lines 1 through 4, but be
    spared typing the examples.

2.  Horrified, and reduced to Lovecraftian psychic jelly by all
    ternary operator syntax.
    These voters could compose obscene ASCII art to express the full
    measure of their contempt and disgust.
    Or use the single word 'REJECT', perhaps punctuated by writing the
    5 examples in proper old-fasioned Python.

Mr. Raymond Hettinger must not be from Chicago.
