While I see where you're coming from with this, it's non-trial to implement this in a sane way, both in code and to handle every possible scenario in a logical way. Suppose I pass an array or 10000 objects which instances of 10000 different classes which do not satisfy the type hint? I guess you'd want to do something like <= 3 offenders - give their class names and indices > 3 offenders - give an error along the lines "passed array elements are completely > wrong" (or maybe report first three and append a "and other errors") ...but IMO the complexity this would add is not worth the effort. From a consistency point of view it should just use the same error logic as the shiny new variadics feature - which also bails out at the first offender. Thanks, Chris
