Since the ? : form is declared unusable by fiat (and I must say I agree,
it overloads the use of the colon too much), it seems only reasonable
that the two intervening things in the ternary conditional operator be
keywords, and both be keywords.  Having one a symbol (whether already
used in the language or not) and the other a keyword (whether already
used or not) seems unclear.
