Here's a somewhat bizarre version, posted mainly for entertainment
value:


{0:b, 1:c}[not a]

or if you don't like the truth-values being inverted that way:

{1:b, 0:c}[not not a]

According to the language reference (which I just checked), "not"
always returns either 0 or 1, so it can be used to turn any object
into a boolean value.
