 namely because aside from equality all of the comparison operators convert their inputs to a boolean and so cannot be placed in sequence like shown here (boolean compared to, say, integer doesn't work). Boolean equality is the one exception which is what no longer works - so the docs are correct.


​Yes, that was poorly written...booleans keep the same type and so can be "chained" while other types do not.  But precedence is not based upon type, just the operator.
