they are not kludgy if one is a bot <wink>

I still prefer

log.info(ok and "success!" or "failure.")
print "auto colorizing turned", self.allow_colorizing and "on" or "off"

over

log.info(if ok: "success!" else: "failure")

print "auto colorizing turned", if self.allow_colorizing: "on" else: "off"
-or-
print "auto colorizing turned", (if self.allow_colorizing: "on" else: "off")

e.g. : seem spurious in an expression
