That seems strange to me. The and-or simulation that was offerd in the
FAQ allowed for about the same kind of structures as the ternary
operator in C and was used in the standard library IIRC.

So the same unreadable was already possible to write, plus that it
could cause bugs and had to be made even more unreadable in order
to work correctly. Considering this it I find it odd that hurting
readability was a motivation not to have it.
