Yep, it was a conscious decision to add a construct with the *potential* to be
abused for use in places where the existing "and" and "or" expressions *are*
being abused and resulting in buggy code.
The code in your example is lousy because it's unreadable (and there are far
more readable alternatives like a simple short-circuiting usage of "and"), but
at least it's semantically correct (whereas the same can't be said for the
current abuse of "and" and "or").
If code using a conditional expression is unclear, blame the programmer for
choosing to write the code, don't blame the existence of the conditional
expression :)
We're-all-adults-here-ly yours,
Nick.
